Sound Distortion Issue Fixed On Custom ROMs (After Flashing Viper) - Xiaomi Poco F1 Guides, News, & Discussion

Hi,
So whoever is using a custom ROM on Poco F1, has faced onething for sure after flashing Viper4Android or any other sound mod; and that is sound distortion when getting notifications.
I see a lot of people asking for a solution and until now we have all been telling them to either remove SoundFX folder from /Vendor/lib and /Vendor/lib64 or renaming the volumelistener.so in order for Viper to work properly.
While the above methods are correct, but it requires messing with the device manually and sometimes it becomes hard to revert back to the original state if necessary (read Bluetooth audio issue).
I have searched a lot for a solution which is more easy and can be resolved instantly if found any bug. And finally I have found a Magisk module which does exactly what we are seeking for.
The name of the Magisk module is NOTIFICATION HELPER REMOVER. It is available on Magisk repo or can be downloaded from here: https://zackptg5.com/android.php#nhr (credit goes to @Zackptg5).
Once downloaded, flash it on Magisk and when asked to choose in between volume up and down, press Volume Down and it will do the job for you. AML is not required. Once done, just reboot the device and send any message to your device and see. No more sound distortion!!
Basically, the module patches volume listener, but systemlessly. Which means you don't need to boot into twrp and mess with the Vendor partition. Anytime you wish to revert back to the original state, just uninstall the module and you are good to go.
I know the module has been there for quite sometime, but the reason of my post is to make people aware of it (since a lot of people actually don't know about it or overlook it).
Please note that I am not the developer of the module and if any credit is to be given, it should go to the developer himself.
If anyone still finds something wrong on this post, please let me know. I will rectify it immediately.

not working for me, I still have the problem with whatsapp . Im in the last version of xiaomi eu beta

When I try to flash notification helper, it is stuck. I have to restart the device.

So I went the route of deleting the soundfx files and now I can't use any type of sound modifiers like equalizers. How can I fix this?

I uninstalled viper and any other audio modules and still have sound distortion. help?

Improved Audio on Oreo Custom ROMs (Ainur Sauron)

I am part of the team for Ainur Sauron, and I am here to present improved audio on the Le Max 2. Sauron has a userconfig which can be adjusted. Download the latest from there and place the attached file at /sdcard before installing. Make sure to remove the '.txt' at the end of the file too! Enjoy :victory:
Impedance is currently set to 16Ω which can be changed to whatever you desire. To set edit the attached sauron_useroptions file and change qc.impedance to whatever your headphones impedance is in Ohms multiplied by 1000 (eg. for 22Ω it would be 22000).
Tested by @I_Raptor_I on his x2, if it doesn't work just send me a log
EDIT: Attached the file
I did not know that anyone else was using Ainur Sauron on LeX2 It really improves the audio quality significantly on Oreo!
Quick question - why does it say "Axon 7" during installation procedure?

Hello GaetanoS.89, first things first uninstall the MK II Magisk module. Now place the given text file in /sdcard folder, then go and flash that module again, it should state that it has detected the user options text file and that's it.

Magisk isn't needed as it'll install with any configuration. All you need to do is placed the attched file at /sdcard (called Internal Storage) and rename it to sauron_useroptions (remove the .txt. at the end).

Did it, and after What I have to do?
@Lazerlord: I tried your mod today by described method.
I copied "sauron_useroptions" into sdcard folder by TWRP file explorer.
Afterwards I flashed latest zip (17.03.) using TWRP. Everything was fine with it during this.
Wiped chache and dalvik and rebooted without any problems.
Result: No ringtone anymore, no message sound, but media sound works fine and was adjustable, no app or menue occoured in regard to your mod. I did not check more.
I could succesfully remove your mod by described method (flash again same file from TWRP)
After removal everything was fine as before :good:

Ah, well could you follow these instructions on the main thread which say "help to extend features". It'll help us fix those issues. :good:
How was the media sound though? Did it sound better according to you?

I removed the "sauron_useroptions" from sdcard folder (as it was described in the file itself, that UO is not mandatory) and reflashed the zip-file again.
With this way everything works !
Will read a little bit the instructions now...
Generaly I have to say I am using Leeco CDLA as headphones atm which are extraordinary by themselves.
So maybe I will use adapter for 3,5mm jack whithin next days and try some user options. Leeco Loadspeaker judgement is difficult imho.
Also new AEX is very good ROM in regard to speaker sound I have to say.
On Oreo 8.1.0. PixelRevenge 15.1 works very well in music playback. He gave me a strange problem. I removed the system camera that I can not install anymore. I had to put another one. I have not tried calls and notifications yet
edit:- Notifications and ringtones ok. In-call audio worsened, the voice is less clear. In speakerphone there is a loud hiss that makes the speakerphone unusable

We're working on a fix for the mixer_paths that'll correct notifications, ringtones, and other audio. I'm happy that you're enjoying music playback. However, the system camera app problem is nothing to do with Sauron it's probably a ROM issue, or possibly even a Magisk issue.
I've installed this Mod by using Magisk 16.0 (v5.6.4) on RR 6.0(22-03-18).
Before I did this I placed the file sauron_useroptions to /sdcard folder.
During the installation Magisk showed that the useroption file was found and used for the installation.
In Poweramp I get the message that there is a problem with app native libraries (libampffmpeg.so).
I don't know whether the error message has something to do with that, but the volume control in Poweramp after flashing this modul is faulty.
Just when the volume is set the half I can hear anything. The volume control steps seems to be broken, but just in Poweramp.(After uninstalling, the issue is gone, but the error message is still sthere)
In other Apps the volume control is normal.
Since I use RR 6.0(8.1) instead of RR 5.8.5(7.1.2) the speaker sounds cheap tinny - Ainur Sauron didn't help to solve this issue. I removed AudioFX, can this be the reason?
It's difficult to describe the issue "cheap tinny", but I think the audio drivers have problems to divorce the difference frequences.
On RR 5.85. the speaker was more "smooth" and the frequences were divorced much better.
Sorry for my bad english and the critic. I think I'm an individual case and other people don't have the problems which I have, but in my case, the Mod seems not to improve the audio quality.

I've heard from @I_Raptor_I that RR already has a loss in audio quality. I advise the use of another ROM and if the tinnyness persists use the attached Sauron zip.
The Poweramp problem is probably due to DVC (Direct Volume Control) in their FAQ they state it may cause issues with 24-bit or HQ audio. The native libraries issue is not related to Ainur as it doesn't touch that file.
About the audio. ROM (which Sauron edits) isn't the only thing that contributes. the HAL and kernel do too, so RR's bad audio may not be able to be fixed or corrected by Ainur but we'll take a look into it.
Ok guys, @LazerL0rd is kindly developing a very nice Oreo kernel for our Le Max 2 improving the speeds dramatically and most importantly audio, he has already optimized our Qualcomm DSP, expect a very nice audio experience on Oreo from now on so stay tuned and make sure to thank LazerL0rd for his hard work, he doesn't even have a Le Max 2 and yet he is spending hours making this kernel for us
Magisk viper?
I have installed viper on RR Oreo via magisk and audio quality is now on point with how it worked through flashing viper and Dolby Atmos on the nugart RR via twrp. There are a couple of things to consider though, viper must be activated before listening to music through your app, viper does not work over Bluetooth by default in viper meaning you must go to viper settings and set mode to compatibility from normal and then viper will work over Bluetooth. The last thing, and I can't remember if this was true on nugart but viper seams to only work with music that you have downloaded to your device and will not work with streaming music from the web.

Reporting bugs
Important: Read the bug list before posting. Anyone can add bugs to the list, just follow the rules.
DO NOT REPORT ISSUES WITH GSIs! Ask the GSI maintainer to fix them!
I will repeat the rules again here:
Rules:
New bugs must include version where error popped up and which oem version you are using
Only reproducible errors
Should include adb logcat, we CANNOT help you otherwise! (linked in a pastebin service like https://del.dog)
Must include clear description what is wrong
If it is a visual/SystemUI bug, only report it here
If it is an internal bug(e.g. fingerprint crashes device), report it to the Sony bugtracker as well!
Always try to fix the bug yourself first! Then submit a pull request to Sony
Must search if error has already been reported (bug tracker, this document, dev buglist)
If you've reported the issue somewhere else already and just want to track it here as well, add a link
Before reporting a bug, always make sure to isolate it. That means, wipe everything, install only the ROM without GApps and Magisk and see if the problem still exists. Only then report the bug!

You can help out with the calibration of the RGBC-IR sensor(named "CASH"
Stick this into /vendor/etc/cash_expcol_calibration.xml https://git.ix5.org/felix/device-sony-kagura/commit/a0253f3de75c52bccb9275ee7eda6cd2f9db539c and tweak the values. You need to restart the CASH server via "stop cashsvr" and then "start cashsvr" after you've modified the values. You can then grep the logcat for "cash" and see the generated values.
The "clear" value is for brightness, you can then adjust the exposure and ISO for the individual steps.

porting of xperia xz3 (pie)
why are developers not make porting of xperia xz3 (pie) to xperia xz dual and use it for stock and unlocked stock?
Which of the 3 versions is the most stable and could be the candidate to remove the official ROM? ... or would I have to wait a little longer? ... I'm tired of not receiving updates, and I get the feeling that the phone is getting slower
When headset connected and playing music (blackplayer) if a notification comes up music stops giving sound but playing. After trying opening volume up & down closing all applications it comes back. Same thing happens if a call comes in when listening music. Music stops but i can't hear any voice from call, doing some things and closing call waiting for the another or i call back it fixes.
Anyone having same problems?

RGBC-IR sensor corrects when? The camera quality is really bad
Hey guys!
Sorry if I write in the wrong place. But I flashed OmniROM 9.0 and have some problems:
- If I call they don't hear me and I don't hear them (Not even calling sounds, tried with 100% working Bluetooth headset too)
- Microphone not work in any apps
- Only the lower speaker works
- When phone turn on the first thing I see after boot animation is an error message; "There is an internal problem with your device" or something like this in my language
- IDK why but the phone slows down extremly for no reason sometimes. But the bigger plreblem is the call problem.

Hello
I have problems with the call audio disappearing.
I installed the system and checked yesterday that everything worked, but for whatever reason today I have no sound during calls.
I have attached the dmesg and logcat Hello
I have problems with the call audio disappearing.
I installed the system and checked yesterday that everything worked, but for whatever reason today I have no sound during calls.
I have attached the dmesg and logcat on del.dog <slash> arepacivaf.coffeescript
(seems I cannot post links due to forum rules)
Based on the output from dmesg, it looks like there might be something SElinux related going on.
I have the same problem with or without bluetooth headset connected.
I am running the latest FTF for my region (192) and OEM version 6.
If you need more info or I should be posting this somewhere else, please point me in the right direction

Make a clean re-install without Magisk or GApps and get a logcat and dmesg from boot until your calling issue.

I installed the system and checked yesterday that everything worked, but for whatever reason today I have no sound during calls.
I am running the latest FTF for my region (192) and OEM version 6.

What ROM are you running? Which version? Did you wipe/format userdata before installing the ROM?

I have attached the dmesg and logcat on del.dog/arepacivaf.coffeescript
Based on the output from dmesg, it looks like there might be something SElinux related going on.
I have the same problem with or without bluetooth headset connected.

It looks like you are running Magisk and GApps. Please clean-install without them and get us a clean log.
Then open an issue at the sonyxperiadev bug tracker.
xda is a horrible place to to actual development, so please try to follow the guides and report bugs in the appropriate places, we cannot monitor everything here.

why are developers not make porting of xperia xz3 (pie) to xperia xz dual and use it for stock and unlocked stock?

For a number of reasons, here are some examples:
Copyright. Sony software is copyrighted and if we "ported" it, we could get sued.
Different platforms: The Xperia XZ is based on the Snapdragon 820 chipset. The XZ3 is based on the SDM845 chipset. They have different CPU architectures and capabilities.
It's hard when you don't have the source. We compile everything from open-source projects here. If you try to port stuff from the XZ3, you have to decompile the binaries to make them work with the Xperia XZ.
Hello there, i have a problem here about installing aosp rom on my XZ F8831 phone, can i ask it here? So i followed everything on your page including latest tft, flashing oem, flashing dsp, but my phone stuck on white sony logo without installing magisk/gapps. When i try to reinstall it but with gapps, i got this message when i try to flash the gapps, "this gapps is for device that have 9.0 android, your device is 8.0" something like that, so i assume anything i do before is useless, because my phone still on 8.0. Please can someone help me? Im sorry for the bad english
Hey guys!
I have problem with Treble on XZ (Single SIM)
I want to try some interesting GSIs but I never able to make any of them work. I tried like 10 different GSIs already.
So if someone can help me telling what I do wrong and someone can help me to make even one GSI work I would be super happy.
So I started everything from the beggining so reflashing the stock rom with flashtool, then flash the modded TWRP oem-vendor and then flash AOSP treble.
Then wipe everything (I tried without wipe and wipe system too not just caches and data. Every combination)
Then "fastboot flash system gsi.img"
When done I turn on phone SONY logo then restart and loop
So I read need to fix dsp (I not really understand this part) but I don't know how to use the codes or if I use them I got errors (I will write down errors if need)
So I used this;
https://sx.ix5.org/files/builds/kagura/misc/dsp-label-fixer.zip
After I installed gsi I turn on phone in recovery mode then flash dsp-label-fixer.zip. Is this ok? Need to do after every single flash or not even need?
Or if I need to use the codes where to write to make it work?;
Code:
[COLOR="DimGray"]su
# It might be either /system/vendor/dsp or /vendor/dsp depending on your device
# Just try both until one succeeds
mount -o remount,rw /system/vendor/dsp
chcon -R u:object_r:adsprpcd_file:s0 /dsp[/COLOR]
When I ask help last time you I get an answer about selinux. I don't really know if it's help or not, but I downloaded permissiver and flashed it. Same question than with dsp. Need to flash every time or after every rom install and before boot it?
What can be wrong? Why I never make trough the SONY logo with GSIs?
I already isntalled OmniROM and Pie 9.0 rom without problem. Even Treble is boot but without GSI, after installing a GSI image bootloop.
I read a lot and watched videos but still the same problem.
I hope someone will help me, I want to learn but I don't know what I do wrong and what to learn exactly. ?
Sorry for a lot long questions and bad English and being dumb.
Thank you for the answer!

WARNING:
YOU MUST INSTALL THE A/B PARTIRION ROM FOR CC9/Mi 9 LITE. IF YOU INSTALL THE TREBLE CHECK APP, YOU THINK THIS DEVICE IS A ONLY PARTITION. IT'S NOT A ONLY!! IF YOU INSTALL A ONLY GSI IT STUCK IN BOOTLOGO. SO YOU MUST DOWNLOAD THE A/B PARTITION
# DOWNLOAD #
First, Download this files. (I recommend install EU Weekly 9.10.31 vendor or after new weekly version vendor)
Pixel Experience Android 10 GSI: https://drive.google.com/uc?id=1Sw96w1J_ZymUh9J7ayhqYrlLZwhuQjJB&export=download (A/B)
after download, extract .zip file!

# INSTALL STEP #
0. You must Unlock Bootloader and install twrp.
1. Move files to your phone and install Xiaomi.eu Weekly rom. after you install done wipe -> advanced wipe -> check system, dalvik, data, cache(don't check the vendor!!) and swipe.

Works way, way better than I would've expected for a GSI.
So far, the only gripes I have with the ROM are:
- The fingerprint reader is not really accurate nor fast, but adding the same finger a bunch of times improves the reliability;
- Double tap to wake is missing;
- As far as I've seen, there's no way to disable the Ambient Display. Normally that wouldn't be a problem, but it doesn't turn off when the device is laying flat for a while nor when it's in a pocket. Kinda concerned with burn-in;
Everything Magisk/Root related works fine, except for Viper4Android or Dolby Atmos.
Didn't have any issues restoring backups with Titanium, so far I haven't experienced a single crash.
Great job, man!
EDIT: So, three things I found out while using the ROM: first, there actually is a way to disable the Ambient Display, yay! Google simply moved it in the display settings, under the section that lets you control how notifications behave on the lockscreen. Weird, but it works.
Secondly, Bluetooth earbuds and speakers stopped working after a while: the phone connected to both devices, but didn't play media through them. Apparently this is an Android 10 bug that happens occasionaly, had to re-do a clean install to fix it.
Thirdly, the microphone doesn't work when sending WhatsApp voice notes. Haven't had time to actually call someone and see if it works there, but I'll add onto this post once I'll check.

Hey man, you still using this rom? how is the experience so far? I plan to install tmr, I wonder if it's stable enough for daily driver
this is very exciting! does this also mean that official pixel experience rom will soon be coming to cc9/mi 9 lite?

TL;DR: Yeah, as long as you don't care about the camera and the stuff I mentioned in my previous post!
Long version: I've been using this ROM as my daily driver ever since, and I really haven't noticed any actual deal breakers.
Performances are great, I'd say on par with MIUI! No stutters, everything feels really responsive and I'm able to hit a consistent 60FPS on high details while playing Call of Duty: Mobile.
DT2W is missing, but I've been using "Always on AMOLED" from the PlayStore, which apart from offering a customizable Ambient Display with burn-in protection also sort-of enables that feature.
The microphone does work, it's just that since I restored WhatsApp with Titanium Backup I had to manually allow the microphone permission. Oops.
If you use Bluetooth Headphones, though, they don't work while using the Google Dialer.
GCam sort of works? There's a 6.2 build for the Mi 9 SE which is kind of compatible, but the experience is really hit or miss. So far, I've not been able to find a MIUI camera port that doesn't crash on lunch or a more optimized GCam.
Apart from that, I'm loving this ROM. It's really all I'll need until a build of HavocOS will be available for our device
EDIT: ANXCAMERA IS WORKING! All you have to do is to download the latest zip and change the "ro.product.device" value to "pyxis" inside the build.prop file ^^

Wait, does this mean that the ROM wasn't modified to enable the fingerprint scanner? If I were to flash another GSI on top of the MIUI vendors would it still work?
since no REAL bugs exist in this rom, can someone take this GSI and patch it to make it only for 9 lite with necessary fixes? thanks!

I got the Viper4Android 2.7 apk from XDALabs, once I installed it I flash Audio Modification Library, the module I linked and after a reboot it all worked
I'm waiting for the release to unlock my bootloader and test ... Is this GSI matching notification icons to notch size?
I was able to install, but FOD didn't work

[GUIDE] Get perfect surround sound from phone speaker with dolby atmos and viper4a

INTRODUCTION
*WARNING USE AT YOUR OWN RISKS*
Though the poco F1 has stereo speakers, the earpiece is sort of weak in comparison to bottom one and so the sound quality falls short when compared to other phones with dual speakers. With this guide, you can make your phone sound much balanced, immersive and better. Basically what it does is increase audio coming out from earpiece by using viper in combination with Dolby. Also this does not increases sound from earpiece beyond max level but instead reduces volume of bottom speaker slightly so it will not damage your speaker
REQUIREMENTS
Any custom rom with magisk and permissive SElinux
STEPS
1. Flash permissiver zip or use SElinux switcher to make SElinux permissive for Dolby module to work
2. Flash viper4a rootless zip in TWRP
3. Flash v4afx zip in magisk then reboot and test if Viper4A is successfully installed and working
4. Flash ACDB zip first in magisk then flash dolby audio zip and then reboot. You should now have moto audio app installed and working.
5. Put XHR WideFX irs file to main storage/Android/data/com.pittvandewitt.viperfx/files/Kernel
6. In Viper, enable convolver then choose the file to enable it.
7. For dolby, the default settings (smart audio) is great but personally I use film mode with surround sound and volume leveller enabled.
I have tested this in evolution X rom and it should work in other roms also. For stock rom it may require a custom kernel. If Dolby Atmos doesn't work then try Dolby Digital instead.
If you face issues like Dolby getting disabled automatically then heading to viper settings and switching Attach Audio Effects toggle or rebooting the system fixes it. If dolby app force closes then reflash it and clear catch after installation

On first choose no then select patch (new logic) then again choose no for notification helper and select remove volume listener library
Even if you skipped it wouldn't matter much because ACP is used just to fix audio not working in some apps and it does slightly enhances audio quality and volume.
For usb dac you can choose yes if you don't use wired headphones from usb c port
For viper though, you shouldn't get that warning
Maybe problem could be in your twrp
Manually mount system in twrp then try flashing again. If it didn't work you may have to reflash recovery
But you said that it is working? Did you tested the audio also? Because the magisk module only installs the app and some configs. The drivers are installed from recovery. You can also tap on the chip like icon button in viper and it should show the driver info and enabled as yes properly

Yes even tho i got warning, but it properly working. I already use it like 6hour, all is working fine.
but when i installing Dolby Atmos, i got bootloop and force me to bootloader. but when restarting phone i can access twrp, just removing them in module via twrp everything is back normal.
but i think it doesnt support latest MIUI Global 11.0.4 ? i got stock MIUI11
Anyway, after wiping module via twrp my viper now doesnt have driver on the app. i already doing the exactly same step 1 - 3 to install viper and it didnt work rightnow. driver still doesnt work even tho i tried installing this many times.
I already go to viper4x thread, someone say need to overwrite 2 file ( post-fs-data.sh & sepolicy.rule ) but still doesnt fix driver.
maybe you know how to ? :laugh:

Dolby Atmos is known to not work as of now in stock kernel or roms for many devices as it is still under development. You can try dolby digital instead
But are you getting the same error on twrp for viper? With system not mounting?
Unfortunately I don't have much idea for viper so I can help you till the limits of my knowledge only
Anybody make it work with Pixel Experience ROM 10.0'
Hi, I want to install it and I have Pixel Experience ROM 10.0 Official. I'm curious if anybody successfully instaled it on this ROM.
Thanks

INTRODUCTION
Though the poco F1 has stereo speakers, the earpiece is kinda weak in comparison to bottom one and so it doesn't give that true stereo like audio performance (surround sound) compared to other phones with dual speakers. But with this guide, you can make your phone sound much balanced, immersive and better with Dolby Atmos and Viper. It actually feels like if the sound is coming towards you and not from the side
This requires the XHR WideFX irs. This is the only one I found till now which worked so perfectly with atmos after testing 500+ irs files.
REQUIREMENTS
Any android 9+ rom with magisk and permissive SElinux
STEPS
1. Install Audio Compability Patch first in magisk then reboot
2. Flash viper4a rootless zip in TWRP
3. Flash v4afx zip in magisk then again reboot and confirm if Viper4A is successfully installed and working
4. Flash Dolby Atmos zip file in magisk (you can download it from guitardedhero's post also for new version) and reboot. You should have both Dolby Atmos and Viper4A working at this point
5. Now to get that stereo sound effect, put XHR WideFX irs file in main storage/Viper4Android/Kernel folder
6. Open Viper and enable convolver then choose the same.
You can now test the sound and enjoy the stereo sound effect. It is best for gaming or while watching movies.
I have tested this in evolution X 4.0 rom and it should work in other roms also but I am not sure for OOS. For stock rom it may require a custom kernel. If it works in your rom then please comment down below so that others could also know it.
If you face issues regarding Dolby getting disabled automatically then heading to viper settings and switching Attach Audio Effects toggle or rebooting the system fixes it.

I have personally tested it in PE pie and Evo X 10 version. But this one should work in any android 10 based custom rom as long as you don't have any other audio mods installed conflicting it or else you may require AML also.

Viper is working fine but after installing Dolby Atmos and rebooting i am stuck at Fastboot, had to remove the dolby module.
Is this related to Miui 11 or some selinux problem??
Please suggest some workaround.
Will this work on miui 11?

Looks like it doesn't work in miui as of now
But you can try dolby digital instead which is also good. Dolby Atmos is still like an early release and currently only works in custom roms and kernels
But remember to choose the IRS file in viper. That makes the earpiece work more balanced. Dolby is just to further enhance the sound quality.

Same is happening in Evolution X I'm stuck at bootloader..
It's not even working in a custom rom.
Works perfectly with Pixel Experience (Android9) + No Gravity Karnel.
Thank you, so wonderful!
Thanks for stereo convolver file, but dolby atmos giving bootloop on miui 11.0.6 android 10
I'm running Pixel Experience Plus Android 10 on my poco. I've managed to get V4A to work but when I flash Dolby Atmos and reboot the device and try to open it nothing happens and after some time and after 10-15 attempts of trying to open it a crash message appears. I also tried installing Dolby Digital Plus for Android Q but that crashes as well

I've managed to get V4A to work but when I flash Dolby Atmos and reboot the device and try to open it nothing happens and after some time and after 10-15 attempts of trying to open it a crash message appears. I also tried installing Dolby Digital Plus for Android Q but that crashes as well

Make sure that SELinux is permissive as they will not work in enforcing
Flash permissiver zip file to fix it
I am also currently on PE+ latest and have not encountered any such issues
My recommendation is use Dolby digital instead as it is more stable (v7.2)

The problem is the volume of the earpiece speaker , I would like to make it louder, but I can't do it yet .
Do not forget to make a backup .

Hello,
Could anybody tell me how to install the mod with magisk please?
Also, I cannot register to the forum of which sanek sent me a link in order to download magisk file because there's problem with russian language.
I've tried to install it with my own magisk but unsuccessfully so far..

Thank you very much Sanek.
I hope this time I will manage to use your mod.
How can I set this mod up? I don't understand how to do it and I've never tried to do such a thing. Please someone help me. And does it work on miui global 11.0.1.0?

need an unlocked bootloader, the presence of magisk or twrp , if you are not familiar with these words, then do not think about modification yet

AOSP Pixel Experience
No effect on Xiaomi.eu
Would be nice to hear from other Miui roms

Yes I have my bootloader unlocked, I have magisk, and I have TWRP, the thing that I do not understand is what is that mixer_paths and where should I put it. That's what I don't understand. Do I have to flash the module, and then the module creates a folder where I have to put the mixer_paths in?

Same here. Latest xiaomi.eu rom and nothing happened but on the other hand the sound on earphones was totally disabled so I removed the module and everything became fine again.

Yeah, this is what I couldn't understand at the beginning as well, but later sanek posted 2 download links, one of which leads to a zip file download. This is what we need. After downloading it, you can just flash it (zip file) using either TWRP or magisk.
Doesn't work
I'm on last beta rom from xiaomi.eu
Works great on PE rom. Thanks
Is it possible to make it work on eu?
Got this working on LineageOS 17.1 before I swapped it to another Rom.
Didn't run into any issues, I will say it was difficult at first to determine if it did anything, I could hear something extra but it was hard to identify I had to get my heavy case that makes blocking the normal speaker silent to figure it out. Once I did I could notice the difference more critically.
Overall, it did add a bit more to the top end I would say.
Bug found on Crdroid 6.6
Mod disables after headphones are inserted and removed. Reverts to only using single bottom firing speaker. Any way to fix?
Pretty nice mod. I would like a bit louder the top speaker, but it sounds great.
