No sound coming from PX5 at all - MTCD Android Head Units Q&A

My PX5 is not giving out any sound, blue tooth, radio, apple CarPlay etc. could it be a firmware update ? Or something going bad with it? Should I try factory resetting it ? Here’s some images of the specs of it. Anyone have any suggestions ?

List all steps taken to investigate. Try rca

Teh crickets

I tried rca, the backup camera works, but still no audio coming out of the system.

Too less information...
You really should take the time to give complete answers. If someone asks you about the steps you did... List them. That makes it easier for you and for all people trying to help.
May be changed the settings to external amplifier? Check that.

[Q] Ideas on JellyBam issue?

Hi, everyone. First I want to thank everyone who takes their time to come and help people like me who mess with things we don't know anything about - such as rooting phones, etc
I installed JellyBam 4.0.0 on my (US T-Mobile) HTC One S S4 earlier this evening. Everything so far seems to be working fine except there is no external audio - no ringtone sound, no radio or music file sound, no notification sound, etc. However, the headphones work fine. I'm not great with tech things, but I'm not a complete idiot, either. I've searched for similar issues and can't find one posted, don't see any settings that may be causing the issue... I'm at a loss.
JellyBam was installed on TWRP recovery and the boot.img was flashed immediately after installation via fastboot. I'm trying to think of what other information from me would prove helpful, but I can't come up with anything else.
So, can anyone offer any ideas as to what the problem (and solution!) may be? I will add that immediately prior to beginning the flash of the ROM and boot.img, I updated the HTC drivers through HTC Sync/Windows 7.
Thanks for any insight or ideas.

Thank you. I just tried that and there's no change. Also went into the sound menu, turned everything down (volume settings) then opened it again and turned everything back up. No change.
I suppose I could walk around everywhere with me headphones on I love this ROM.

Do you think he might have to do what I did for the sd card, maybe that will kick in what he is missing plus doing the full wipe and re-flashing the ROM just wondering?

No its an old bug that's been there for as long I can remember lol but changing the volume should fix it.

Just to make sure I understand (because I am technology-challenged), when you say changing the volume - I assume you're talking about either using the volume rocker on the side of the phone or simply going into Settings > Sound and changing the volume sliders there.
Correct?

Ya I mean the first but both ways should work but do it without the headphones.
---------- Post added at 04:13 PM ---------- Previous post was at 04:11 PM ----------
Oh just popped in the head but try having music playing and do it.
I did. Tried it when searching ring tones, then tried it with Google Music playing a track, tried it with local radio playing and tried it with nothing at all playing.
So let me ask you this - can I make a backup (Titanium Backup) of all my current settings so that when I wipe/reinstall, I don't have to redownload all my apps and redo everything?
Lol - I gotta say, though, as irritating as it is to have only this one issue... I love this ROM and the way my phone works with it. It's worth the hassle if I can get it fixed. (Especially considering I almost bricked it yesterday before finally finding this ROM.)
I should really not mess with stuff I know nothing about. But I just can't help it.

Load TWRP and do a backup there, then still in TWRP do factory reset and reboot and skip over the signing in stuff and then try playing with volume without plugging in the headphones and if this still don't work you could try in TWRP factory reset and then system and them reflash the rom and if this still some how don't work you can restore the backup in TWRP.
Ok, I'll do that now - but first, one more stupid question. After this, I'll leave you alone.
When I first installed this ROM, I went through Fastboot to flash the boot.img. Do I have to do that again if reflashing the ROM, or can I skip that step?
Thanks for all your guidance. Seriously.
Update on thread
So I followed the instructions above.
Went into TWRP, did a factory reset and rebooted. Played with volume. Still no external audio.
Went back into TWRP, factory reset, wiped system, reflashed ROM (did NOT manually reflash boot.img in Fastboot) then rebooted. Played with volume. Still no external audio.
Went back into TWRP and restored the backup - so I'm still left with a killer phone with no external audio, ringtone, etc.
Hmmm.... hope nobody calls when I can't hear/feel the vibrate or have my headphones in
That's strange though - I find no other threads mentioning a glitch like this and, except for this one issue, the phone/ROM works flawlessly. It even fixed the wifi connection problem that always existed with the stock phone/ROM and I know a lot of people with this phone have had that problem. With the stock, the wifi always had a problem (from the first day) connecting to my home wifi. Sometimes it would connect but normally it would take a long time (an hour or more) before finally connecting and still other times it wouldn't connect at all. Now if I leave the house, it connects as soon as I pull up in the driveway and if I power down/reboot, it connects instantly upon reloading.
Just before installing the ROM (the first time) I connected with HTC Sync via my pc/usb and made sure drivers were up to date, which is why I'm thinking it's not a driver issue. Would you agree?

Ya not sure what's up if you still got your backup you could try another rom like CM10 to see if its the same. The wifi confused me, everybody else find AOSP not as good at wifi, for me Sense let me set the router how ever I want but on AOSP I have to have it at default settings.
Final update on this thread
Earlier, I wiped everything (through hboot) and reflashed JellyBam. Once rebooted, not only did I still not have audio, but the wifi connection went back to normal - it would connect, but not without difficulty/delays. Strange,
Since I can't feasibly go without a ringtone/alarm/notifications (I use my phone for my business) I rewiped everything from TWRP and installed Dark Jelly v23 to include the Fusion Ultimate kernel. On first boot, still no sound but the notes here mention that may be an issue until it's rebooted a second time. So I set everything up, played around with the same ideas we were using earlier in this thread (to no avail) and then rebooted.
Wifi is the same as it always has been (with the exception of the glorious several hours when it worked like a champ on JellyBam). That's no big deal - I'm used to it and know it's an HTC One S quirk.
But....
Sound is back :good:

General ROLL-UP -Joying 2GB - Sofia ( Non MTCB/MTCD )- Tips, tricks and mods

There is getting to be quite a bit of information to look through when looking for tip/solutions related to the new Joying 2GB / Sofia units. Since this is not a MTCB or MTCD unit, the threads seem to be scattered all over and very difficult to find in searching. I have seen roll-up threads for other units, that contain information such as ROMS available, tips, tricks and useful information. Kind of a "one stop shop" for the newer Joying HUs. If you have useful software, mod, tips, customization's, get something to work, etc please post here and I can include.
CPU Information - Rockchip Sofia x64 C3230RK / mali 450 GPU / Up to 1.2Ghz / 4 core / FYT5009 SoM - rated to run at up to 85C. My particular is unit clocked at 1.04Ghz.

https://forum.xda-developers.com/an...d-units/joying-intel-update-feb-22nd-t3561285
People have experienced issues with the Joying Launcher (UI3) after the update. This seems related to having other packages (google voice search ) installed prior to installing the ROM. Install time 25-35 minutes.
Recovery from non-bootable system - Without being able to access recovery, about the only solution is to reload the ROM package. Unzip ROM to SD card or USB stick, put in unit (GPS Maps slot, if using SD card ) and press the 'recessed' reset button. The unit should find the update and reload the ROM. This will wipe your data, but does leave the apps. If you use titanium backup, and have a backup, you can restore your data fairly easily. See blog article above for step by step instructions.
Root - Unit comes with root accessible in adb. SuperSU can be installed easily. There are 2 methods for installing superSU. The first method is an overwrite of the boot partition with a pre-rooted image. Problem here is if future upgrade makes boot partition changes, this method will overwrite with an older version. I recommend method 2, which modifies the existing boot partition ( need source so I can provide credit ).

https://drive.google.com/file/d/0B4qmTV7N4JliSjZMdGg3Z18wbkU/view?usp=sharing ( modifies existing boot partition )
OS & Google Apps - Android 5.1.1 ASOP based w/ pico installation of google applications. Voice actions are supported with installation of 'Google App' from play store. No support for google search talk back.
Recovery- A recovery partition is present but does not have any type of graphical UI. It does look like a complete stock android ( command line ) recovery, but no access using USB is available. It maybe be possible using PC-PC OTG cable.
SD Cards - I have not heard of any sdcard size limitations, up to 200GB have been reported to work. Must be formatted as FAT32. NTFS, exFAT, and ext3/4 do not work. You can format a USB stick with ext4 and it will work fine.
Google Voice Calling - Stock BT dialer crashes when being called from google applications ( such as google voice search ). Workaround is available.

Apps not working after resume - The joying code will kill most applications when going into standby. This is really bad for apps that are supposed to be run at boot and background process, as they are not restarted when exiting standby. Symptoms include, widgets not updating, apps not getting GPS lock, process show running but background services are no longer running. This can be fixed by installing an updated apk file in /system/app/Sofia-1-C9-Server-V1.0 which removes the task killer. Also the key/button mods V2+ (below) will remove the task killer.

Phone/Tablet view on apps - No app needed - Change from 160dpi -> 161dpi gives "phone" view of many apps instead of "tablet" with no noticeable size change to other things. Done via adb. Requires reboot to take effect.

Yes this is really needed. A FAQ with overview links and tips in just one post
Some people mentioned it was possible to boot into a restore function from a memory card with the update zip. If true, do we know what the exact process is? Any keys need to be held down?
Update, verified this procedure works:
sonof said:
I did recover from endless Android logo (resulting from trying to root with Joying HU root.zip found in this thread).
I did the following:
Put latest Joying update files to microSD card and insert it to GPS slot. Press and hold both reset and power buttons. Once it boots continue holding reset button.
This lead to automatic install of Joying update files and my HU was back alive but I hate the Joying company for not providing means to enter recovery and a complete ROM.
Edit: For me it did not ask if I want to update or not. It just began updating automatically. In contradict to the post above. But I was unable to boot to Android when I tried this.

My VW has reverse parking sensors. Does it not support those?
Just installed this unit. Speedwise it's night and day compared to my old Erisin (1gb 3188). Display is nice and crisp. Bit of a fiddle getting it mounted because of all the crap that needs to be stuffed behind it, but after some swearing and elbow grease I got it secured.
From the instructions, I cut an orange wire because I don't have a backup camera. I do however have optical parking sensors. On my Erisin this was supported (it showed a car model and visual indicators on screen). This unit doesn't appear to have this function. Can anyone confirm? I still get the beep from the speakers, so it's not really a big issue, but would be nice to know.

I'd like to work on this one.
But I have two questions;
1) did you manage to get any logs of how it failed?
2) When you made it unbootable, what was the exact procedure you used to recover the unit?
Click to expand...
Click to collapse
I didn't get any logs, as I couldn't connect to it until I reloaded the ROM. If I was able to make a USB connection, at least I could have looked at the logcat.
Procedure to recover: Insert USB drive with ROM, push recessed reset button, wait 30m for ROM to install, set up apps again. I have this procedure down pretty good. - The joys of playing with the system partition without USB access or recovery tools.

Actually, it turns out it does, however only when there's an obstacle (hopefully we can change this). Yesterday I only tested while stationary. Today I used it while driving, and noticed that whenever the sensor picked something up, the unit does actually display the sensors. It feels next to useless for me when it only shows on beeps, but at least we know it's there.
Well, that is the way my discarded Newsmy worked. Takes getting used to, but you then again you don't really need confirmation that "nothing" is in your way
Will need to think about this then, thank you.. Cant make up if I want this or the Ownice C500.

After updating to the January firmware parking sensors are gone completely.
edit: enabling "radar" is the solution
Installed supersu (like described in this thread) yesterday and updated it from the play store. Worked fine.
Then I installed Viper4android, also from the store. I didn't expect it to work, but it does! Driver installed, and after a reboot it does exactly what it's supposed to.
Also installed Nova Launcher and set as default home. No issues with that so far. I have not frozen or uninstalled any of the original launchers.
On my Joying unit 130N2 (8 inch unit for VW) the backlight on the display does not work when it is cold. We had minus 8 degrees centigrade here and it took more than 10 minutes before the backlight came on. The radio is playing music and it is actually possible to change channel as long as you know where to touch the monitor. Today it was 5 degrees and it took only about 3 seconds before the backlight came on. I wrote Joying about it and they confirmed to me that there was an issue with 8 inch models for VW. They told me that they were working on a completely new firmware that would fix the problem. I told them that to me it seemed to be a hardware problem and how they wanted to fix that with a software. Their answer of course "No worry my friend ......". I told them that I wanted to return the radio because a radio that doesn't work when it is cold is useless to me. They told me that I would have to send it to China so that their engineers could investigate the problem. I then told them that I had bought it from a German website and it was delivered to me from Germany so if their wanted it to be sent to China then they would have to pay me for it - in advance. They told me that their warehouse in Germany did not accept any returns so it was impossible for me to return it. Then I opened a case with Paypal for selling defective merchandise. Then suddenly their warehouse in Germany was accepting returns. I had put this text also on the Joying Forum, but of course they deleted it. So when dealing with Joying and in case you have problems my advice is to be very tough on them otherwise they will BS you.

I have the same problem on the same unit. With the car headlights off, backlight is dim when it's cold, but gets brighter when it has time to warm up. And when the headlights are on, the backlight isn't on at all until it warms up.
I thought about writing Joying about it but I expected the kind of response you got. Plus, I've had my unit for a few months already so a PayPal claim isn't an option. Please let us know if you hear anything else about it from Joying.
Hi Joshnat,
Yes we have the same problem. Sometimes I can get mine to light up by turning the headlights on and off a couple of times. Are you sure that you cant make a Paypal claim? As far as I know you have 180 days.
Anyway, you should write to them and let them know that you know that many others have this problem.
Regards
Kurt

You may have a faulty screen, my first one did something similar and wasn't very responsive to touches. I returned and my second unit was like night and day with how much better it looked and worked.
Has anyone got a factory backup camera to work? I have a 2015 Camry and right now I have the older Pumpkin rk3066 and the place that installed it hooked up the factory backup camera. I got my new Joying hu yesterday and am going to install tomorrow myself. I'm really hoping I can use my factory camera with this head unit also.

https://www.amazon.com/gp/product/B01BM3QGCO/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
Quick tip:
You can adjust backup camera brightness, saturation and contrast by touching the screen while backup camera is on.
Is there a trick to putting in the sd cards? Mine won't click in so it won't mount.
Edit: Forget it i just had to get the edge of a screwdriver and push it in. Had me worried for a minute.

Does anyone have a link or info on the dummy proof DIY on how to Root the joying unit? I want to install some of these enhancements so need to root the device and have never done it so was looking to see if anyone has a link or good write up for the slow like me. Appreciate it. I have a Joying 2gb 7 inch unit.

Within the zip there is a file with instructions - HOWTO.txt
How-To install:
1. You need a Windows PC that is connected to the same WiFi network as your HU.
2. Unzip the attached file somewhere to your disk.
3. Run CMD.exe as Administrator
4. Change directory to the folder that you unzipped.
5. Run the install.bat script with an IP address of your HU as a parameter:
C:\Users\<username>\Downloads\Joying_JY-UL135N2_SuperSU> install.bat 192.168.123.137
6. Wait until script finishes and reboot your Head Unit.
7. DONE!
You should now have the SuperSU application working.

Android Stereo Head SWM 8802 Guide

i recently purchased an Android SWM 8802 from eBay. This was my very first car stereo swap. The manual described the software functions, but unfortunately didn't show anything regarding the hookup and connections. Additionally, the manual was in such small print I couldn't read it. I started to photograph it and blow it up, but it didn't seem much easier.
I do enjoy writing how-tos and helping others. Would anyone be interested in such a guide if i were to write it? I haven't tested everything such as the rear inputs for video ( although I am working on that). There are little things I've found such as the insertion of a MicroSD card that, if not entirely scanned first, will only play up to what it has scanned.
I'd like to make it more for newbies as well, or have at least a lowest common denominator. Would it be worthwhile doing this with or without contribution from others, or is it more of a niche thing?

I have a dedicated camera set to a separate dashcam / backup screen, and haven't had to mess with those. I think you may be stuck with that since the monitor isn't controlled by any Android type of software.

I've been thinking about this, but keep in mind I haven't gotten any video on my monitor yet. What is the resolution of the camera? Maybe it's too big or too small so that the reverse guidelines aren't accurate.
phone link issue
hello, i bought the car radio andoid swm 8802 and when trying to connect to phone link - gives me an error to go in mob setting - developpers option - usb debug to allow . but have nothing on my samsung s9+ about that can someone help thank you in advance.
Mine seems to be working ok after a couple of months. The GPS stopped work so I figured it just needed a reboot, but I couldn't figure out how to do that. Long press on the main button just seems to turn off the screen. In the end I pulled the fuse out. When it restarted there was the swirling car logo and I had to reset the time and a couple of other things and, lo, the GPS was working again. If it stops it would be nice to be able to reboot without pulling the fuse again.
I have set up the SWM 8802
Some how I switch out of english
I am not able to set the time
I can not get to setup
Does anyone know how to do a reboot to get the factory settings
The reset does not reboot The changes have all been saved

I am struggling along...
I swapped my 2017 Horda Ridgeline PH-3804 Clarion out for the SWM 8802
Somehow I have changed the language from english and cant return...
I can not set the clock...It has set eastern time with GPS
I have radio and bluetooth working but can not get to setups
I think I have to reset or reboot the ROM to get to factory settings?
The reset does not reset the ROM changes...
I have looked at posts for 8.01 firmware upgrades but can not figure them out?
Any idea of how to reboot the SWM 8802? I have to start over to return to
english and get clock set and settings...
I hope USB to USB B adapters that will arrive shortly will connect sat receiver and the
CD player and the back up camera...

Samsung Galaxy Note 9 and Galaxy Buds Bugs and Errors

Hello there! This is my first time in this forum so I apologize if this is not the right place to post this.
So, I need help with my Note 9
SM-N9600
One UI 2.5
Snapdragon I think
For a year or so now I've been having trouble with:
- Losing volume in my earbuds
- Experiencing lag in downloaded videos in Nike Training Club and Samsung Health apps
- And most recently the Google Play Store and LBRY apps have crashed a lot
It all first started after installing tutuapp. at first it was all normal but after a few months I first noticed my buds coming low in volume. Of course I visited every possible thread and blog and advice on the subject but nothing would work so eventually I went to a Samsung store and they offered to reinstall the firmware so I did.
It solved everything! until dummy me I reinstalled the app. It took a couple of months to realize that tutuapp was the source of all my troubles and when that happened I never installed it again, but... I now installed an APK and it happened again. It's worth mentioning that at the time I would only notice the low volume because I didn't use the exercise apps.
Anyhow, reinstalling firmware fixed it again and again (It took me a bit realizing that the APK was the source of trouble) until it didn't and now no matter how many times I reinstall it, my right bud is lower on volume and my left bud just sounds weird. Once I did a reset on the cache memory and it actually fixed the buds volume quality perfectly, although just for about a day and then back to broken.
So far it is clear to me that Samsung has no clue as to how to fix this issue nor care to fix it really, they find any little excuse to make their job easier instead of fixing stuff in my experience. Anyway, It's been so long and I'm a bit desperate to know exactly what the problem is, let alone fix it so I appreciate any help fixing this.
Please and thank you.
P.S.
I have posted this already in the Note 9 section but I posted here aswell due to an admin's advice as to get more exposure, a quicker answer and hopefully the attention of some android pro/veteran.
Verify the Buds are working normally on another device. If good try steps below, if not you got corrupted firmware on the Buds. Only Samsung can fix that.
Make sure your Wearables and Buds firmware are current.
Clear system cache, do a network reset and a hard reboot.
If still there start going through the settings. It may have toggle a visible one. Look under Advanced Sound Settings, play with those.
Go into Developer options and try toggling the codec setting, sometimes that will cause the needed reset.
Play with it.
It's better to find the root cause than to factory reset if possible otherwise it may reoccur.
If those don't get it... it likely is a hidden setting was toggled. Factory reload and don't use SmartSwitch!
Poorly 3rd apks that don't uninstall cleanly can break Androids. Limit apk sampling and well... now you know one of the risks. Being on Playstore is no guarantee something like this won't happen! Sample what you want now before the reload; install only known good apks after the reload.
Fun times, huh?

Advanced sound settings and codec settings... do you mind elaborating on those? What am I looking for exactly?
No smartswitch... why is that?
The thing that makes the most sense to me is a hidden setting since I have tried everything for so long... but which setting?
Thanks for the quick reply

Can say precisely where it it in Advanced sound settings as a Wearables update modified it on my device, that option is gone. Took Samsung years to fix that.
In Developer options it's under bluetooth settings.
If it's a hidden setting you have no access to it normally. You may be able to purge it by clearing the parent/dependency app's data. Obviously as a factory reset removes it, it's on the userdata partition but finding it can be difficult with no direct access.
Sometimes clearing system apks data in settings will leave a null mark and it will continue to misbehave. Been there, done that...
I know that Package Disabler will completely clear the data. In your case that's probably not necessary. In my case PD MDM saved me a factory reset, one reason I wuv the app.

Thinking about it... I don't think the issue is so directly connected to the buds. I feel like the buds and these apps are just side effects, if that makes sense. Btw this very app is starting to crash aswell as LBRY.
Some time ago I reinstalled the firmware and applied a backup and because tutuapp was in the backup and the samsung technician told me those apps cause trouble, I could delete it and fixed it after another reinstall, that's when I discover the real cause.
Having said that, I think the issue remains inside some file or setting I don't ever look at or change and hides in it. It may sound weird but something like a contact or photos or something, and I mention those because I don't change anything around those places but then again... I'm just lost.
Anyway, thanks for your help, I'll look around your suggestion and if what I said above makes sense, I'd love more ideas.
Cheers
P.S. Bluetooth Audio Codec, found it!
It was on SBC, there are several options:
SBC
AAC
aptX
LDAC
Scalable Codec
All Codec
System Default Codec
Funny thing, if the option selected is not SBC, the word "streaming: AAC" appears in each case

You're welcome.
First use another device to verify the Buds are working normally before you go all medieval on the phone. Buds tend to be very reliable but you know how that goes.
Sorry, forgot about SmartSwitch. It's ok to use on the same device/OS version otherwise don't particularly if backing up settings.
In your case it could import the setting causing this issue.
Next reload be careful what you load. 3rd party apps have the potential to cause a lot of trouble. I watch my downloads and apps like a hawk.

Yeah, after I solve this all 3rd party apps and apks are out of the question lol.
I have test the buds several times and it's definitively my phone, it sounds weird with every kind of earphones I have tested.
I snooped around the Codec thing and while it improves the audio quality, unfortunately I can still distinguish the bug in there so I guess I will just have to come up with something else.
Thanks a lot mate!

Try doing a reset in the Wearables app that might purge the gremlin.
Wearables just updated, as usual Samsung made the interface worse, idiots. They buried the equalizer in the menu and put ambient sound control on top. A useless function I never use... morons. Guess I call them and chew them out a spell... I enjoy that

Oh, I feel ya. They really care about selling fast against apple but leave all these products behind. Their customer service also sucks, they are only there to tell you that the bug is in you, not the device... it's horrible, it's a pity for such a great capable phone...
P.S. Just tried the wearable thing but no luck. I was just remembering that the last apk which I installed and broke everything for good was the note10+ star wars edition firmware... and of course it had a much bigger impact on the phone than tutuapp and other hacks for games... any known bugs from installing that?

Getting SK Samsung tech support on the phone is something I relish like a demon. They can not handle criticism at all and I just lay into them.
It's a cultural thing. They can't solve problems either which is probably just crap training.
Nothing should break firmware that a factory reset can't fix on Pie* and above. That sounds more like a rootkit than a just bad app. It may have damage the hardware if a factory reset didn't fix it.
Be careful what you install...
*pre Android 9 OS's are vulnerable to rootkits that can breach the userdata partition, a reflash is required to purge them. That vulnerability was patched on Android 9.
When you factory reset you wipe the userdata partition and viruses, rootkits, corrupted data, whatever ceases to exist.

Most def crap training, they know nothing but to make a quick reset or factory wipe...
Anyhow... that makes sense! I don't want to ask how does a rootkit damages hardware because I know it will be an extensive topic but if 3 firmware reinstalls (by this I mean firmware glash with odin by a samsung tech guy) didn't fix the issue, then for sure it is a hardware thing which makes things so much worse for me because it sounds expensive! Lol
How do I check my hardware's health?
P.S. is there any cheer pointa or medals I can give you throigh the app? I want to show my appreciation because you have really listened to my problem man. Even if I don't fix this, thanks a lot for your help and dedication.

Normally rootkits don't fry hardware but the firmware controls most of the hardware.
If the rootkit can't breach the userdata partition I doubt it would be able to damage hardware. I may be mistaken though.
You check hardware by function or lack off.
Not sure what advance testing is available for Android memory and the CPU other then bench mark apps... never had to do it.
It may have been damage by a drop or just a failure with no discernible cause. While the mobo has thermal auto shutdown it's still possible to overheat and damage components.
Especially if there's a fast temperature rise.
If it's the mobo you just replace it...

Mobo ie Motherboard.
Good Q, the sim isn't directly connected to bluetooth operation that I'm aware of.
Here's a guide that might help you and shows some specific settings to try:
Redirect Notice
If streaming from the SD card, does its bandwidth support the thru put?
Try playing with these...

Don't know. I just keep playing with it and reading about similar issues until I fix it.
Try in safe mode.
A 3rd party app may alter settings hidden from the user.
Or the solution may be hiding in plain sight. I was having a volume issue (went on for months) with a browser vid player until I realized it had a hidden volume slider by the mute button
Factory reset if you're desperate but it may reoccur.
Alright then, thanks and cheers!

Media storage got crazy on my old Android 6 Lenovo phone

I don't know what has happened to my old Lenovo Vibe X on Android 6.01 and how to resolve the issue without wiping data (no guarantee it would help - I'm now thinking...).
The phone is temporarily at my relative's disposal: i've switched to her Google account to let her use my old phone. She complained the call ring was very weak. I decided to change the ringtone, but I found out that I cannot do it anymore, the Media/Audio/Ringtones folder with standard OGG files is not visible (I cannot select ringtones from there anymore). "Other ringtones" option directs me to some installed Audio player, which does not allow to select any MP3 files in ANY folder (they cannot be played, because the player reports they are not added to Media storage). When I try to use "Scan media" option - it is just stuck. I've tried to use another programs like SD scanner, they either report Media database read error or finally report success status, however the audio files are still not playable.
I've tried to: clear caches (Android and Dalvik), disable / enable Media system app and delete its data.
I've also noticed that NOW my USB Audio player reports that HiRes DAC is not found (!) and does not want to play files in HiRes mode (through the chip instead of generic driver) - actually, my phone does have ES9018 DAC...
I am not sure this problem is related to Media storage, however all this together is very weird.
Any thoughts what could happen and what should I do?
How long was she using it and how good are her Android skills? May have caught a rootkit or virus. Anything below Android 9 is vulnerable to the Xhelper type rootkits that can worm their way out of the user partition. Real nasty critters...
If it just went nuts, I highly suspect malware especially in the hands of a novice user.

As @blackhawk wrote, the user may have infected the phone.
The only solution is to flash the phone manufacturer's stock ROM.
I will try to do this as soon as I get a chance, nowadays there is no other smartphone to use for my relative, so have to wait a couple of days.
BTW - regarding "HiRes DAC is not found" message... is there a chance that guys who replaced the battery in this smartphone soldered out ES9018 chip??

Likely a software, firmware or settings issue. Malware could also be the root cause for losing the high resolution DAC.
It's possible the tech damaged this circuit but probably not likely. Obviously if it was working before they got their paws on it then they are likely to blame.
