How to Enable ViperAndroid Fx 2.7 Headset Effects Through Car Speakers MTCD PX5 - MTCD Software Development

I was using Viper4Android in my old Android 6.0.1 head unit without any problem. I did use headset effects on my car speakers. There was an option like "Lock settings to Headset" or something like this in options menu.
Now I rooted my Android 10 device and installed ViperAndroid Fx 2.7 and it's driver successfully. But only effects under the speaker menu are working. I just looked options menu but didn't find any option about this.
How can I enable Headset effects on my car speakers?

Hello,
You can't. I spent a lot of time to find out how to do the same, I finally found a message on the viper forum in which the dev said that they locked the effects on the BT output during a major update in 2018 or 2019, It was intentional and they didn't plan to change this.
I tried to use an older viper version on my mtcd, my unit bootlooped so I had to revert back to the embedded version (Android 9 for me) .

I know Viper needs "audio compatibility" to run for my phone if your unable to uninstall then you could try to use that
Havnt tried on head unit

sound effects/equalizer not working

Hey there all I'm running stock android KitKat 4.4.2 rooted with CWM and I have notes recently that the sound equalizer option in the sound configuration menu is disabled even though the MusicFX is enabled in the device, I tried installing Volume+ as a temporary fix and when trying to open it it crashes.
As a reminder when setting the android sound enhancer, it doesn't matters which I choose they both crash.
Any ideas about what causes them to crash and a possible solution will be appreciated and tested :laugh:

Has Android 6 some equalizer implemented? Settings to tweak? (Not Viper4Android)

Hi.
Android apparently has some sort of equalizer. When I play music is sounds better but louder than voice, which sounds distorted.
I assume there are different equalizer settings for each.
Because voice sounds distorted I wanted to search for something tweaking the settings.
Currently I only know Viper4Android, which has to be installed as an app.
I cannot use Viper4Android, so I wanted to search for some Equalizer settings built in Android 6.0.1 itself.
Could you help me finding them? Is there anything to tweak them (build.prop)?
Where do I start looking?
Specifically it is about my smartwatch, the speaker works fine but in phone mode the voice is distorted.
I want to find some way to tweak this.
Asus Zenwatch 2, rooted

Will changing ROMs change my sound output?

So I have spent many hours with my aftermarket sound tuner (OEM Audio+) and they have gone to great lengths to tune the aftermarket amplifier to sound perfect with my Joying HU.
I am not sure what the factors are that will change the sound but will updating to a Malaysk rom (or updating in general) change the headunits internal EQ settings or are all MTCD roms typically the same?
For clarity, would flat EQ (on current ROM) vs flat EQ (on Malaysk ROM or updated Joying ROM) sound exactly the same?
I have the new Joying 5.1 Toyota (200mm x 100mm):
MTCD_JY_v1.63_1 (Jun 12 2016)
Also side question, does anyone know why Google maps mutes my music or how to fix it? =p
Thanks.

Extremely low Bluetooth volume

Hi,
I have an issue with my Samsung Galaxy S8+.
If I try to play music via bluetooth to my speakers, the volume is very very low. The settings are on max and media volume sync can't be enabled.
I tried playing music with my Samsung Galaxy S7Edge and the volume was completely normal and very loud with nothing changed on the speakers.
I also tried this: https://forum.xda-developers.com/galaxy-s8+/how-to/low-bluetooth-volume-car-fix-t3595530 with no result.
My BT speakers: https://www.trust.com/en/product/19367-tytan-2-1-subwoofer-speaker-set-with-bluetooth-black
My S8+:
Android 8.0.0
Stock
Knox triggered: 0
Never did any manual flash. Always just updated it.
Are there common reasons for this or good fixes? Or is it just a software bug?
Thanks for your time!

It's oreo, they messed up the volume and everything audio on oreo, no fix right now I'm going to make a topic to see if it's possible to downgrade back to nougat.
Not just an Oreo thing. I've had the same issue with the Bluetooth in my car as well.

Look at that post. I tried the force close method and it helped.

it's amazing that you can't tell the difference at all, it's very noticeable, i am unable to hear anything when i receive calls in my headset either, this latest oreo update is broken.
found something online, it's something to do with media sync, try connecting the bluethooth device, then go to settings, bluethooth, 3 dots and select media sync, select on and make sure both phone and headphones volume is max and restart phone, anyone notice any difference? i'm testing it now.

Yea that was the first thing I have read about when I started searching for it. I wanted to try it, but it seems like my BT speakers are not compatible with it. It says that it isnt compatible when I try to activate it. Not sure if there is a workaround to make it working.
I don't think this is an Oreo specific problem. I've encountered this bug since marshmallow.
The only way I could get it to reset the volume back to max was when I used crdroid.
The volume would get set very low. I could open the global equaliser via Google music. And the volume would not change.
I would then access the global eq via another music player. Just make a tiny change to any parameters and boom. The volume is now set to the correct level again.
The moment I would use Google music to access the eq the volume would jump down again
My tablet is now on naosp and the volume issue has popped back up.
Doing the same procedure will reset the volume correctly.
It is rather annoying to have to do this.
I don't know what is causing the problem but it looks like the global eq ultimately effects the output volume disabled or enabled

No difference at all with three different devices I connect to. I do have media sync disabled already. Hopefully you get it figured out.
I've done a test on my S8+ now.
I downloaded the latest firmware and flashed it with a complete reset of the phone.

After the flash of it the BT issue is gone. This was done yesterday (4/10/2018). I will report back if the BT issue returns OR in like 2 weeks+ if everything is still fine.
GL everyone
new firmware released by samsung, lets hope this fixes the issue :S, i checked the notes and it does say fix for bluethooth.

do you need root for that though and i never had this issue in nougat, this issue first happened in oreo.
And i have a universal eq setting on a separate app called precise volume which does the same thing.

It dosn't work anyway, still the same, on a good note they have fixed the low volume for incoming calls on my headphones, just the music volume is still crap.
I think my only solution is another set of headphones that support LDAC but they are £300+ lol or to get a Microsoft music player, i have a laptop that even beats what the old volume was on nougat so maybe a Microsoft music player would be a good idea, gonna look around.
It was good while it lasted i guess.

I wasn't rooted before but since then have rooted via magisk systemless root. I can still use pay and bank access etc...
I'm using viper4android now and have also disabled the system EQ.
I have just got connects2 for my car last weekend.
On the odd occasion the volume will drop when opening automate(the driving launcher) which is set to launch playmusic on Bluetooth connection.
But as soon as I swipe down the volume jumps back up.

So you think it's worth rooting and do you notice any difference in audio quality?

Yeah for sure but be aware you might loose functionality on apps like banking and payments.
I use magisk to hide root so I can still use those functionalities.
Make sure you read into it first.
I've had a replacement connects2 module fitted today and all is going well.
Viper4android my EQ is absolutely amazing in comparison to other EQ and in my case the volume issue has been solved.
Actually it's really loud as I was used to the lower level.
Steps I took.
Unlock bootloader ( wiped my tablet)
Flash magisk
Install magisk manager
Added selinux module via magisk manager
Added viper4android via magisk manager
Disable global EQ
Set selinux to permissive
Install viper4android driver. Prompts when opening the app for the first time.
Reboot
And it's all good.
The bug with AutoMate seems to be tied to my maps speed prompting notification voice.
If it does revert to no EQ, I drag down from the top bar and it's back up again
I hope it works for you. Plus you now have a very awesome EQ as a bonus

Try enabling Developer mode (press Build Number 8 times). Then turn on Disable absolute volume. This de-links the phone volume control from the headset's volume control. Now you should be able to increase volume on both independently.

THANK YOU SO MUCH FOR THIS. I had two pair of bluetooth headphones. A Cheap pair with volume control and a fancy pair of JBL Frees with no volume control. I could NOT figure out why sometimes the volume was great when they connected and other times it was VERY LOW all the while the cheap pair sounded great when I turned them up. I was at wits end blaming JBL and Samsung when it was a setting for Bluetooth devices.
Thanks again Huyi. Very glad I found this post.

Android 10 headphone volume even lower than pie? any suggestions?

So before updating I had a couple of sound mods because the stock volume is way too low for me. But after the update I did a wipe ofc and now I can bearly hear my music. I installed the volume booster magisk and viper4android but there is no difference. The only thing that I did before different was editing a file in /system/etc. Something like volume limiter. It was at 80 something and I changed it to 99. But after the update that file doesn't exist in Android 10 apperently. I'm rooted and I know my way around modding and stuff. Is there any way to boost my audio volume? I'm talking about Bluetooth headphones btw...

Am I doing something wrong? What settings do you use?
I had the same problem. Pie was crappy. Q is horrible for Bluetooth volume.
I fixed Pie by installing Viper, but I cant get Viper to install its driver in Q.
This might be why Viper doesnt work for you, either. It isnt installing its driver.
I did find a way to increase the gain in Q though.
1. With your headset connected, press Vol + or - to get the pop out menu.
2. Press the little EQ icon under the volume menu.
3. Press the gear icon for the "Sound and Vibration" settings menu
4. In that menu, press Dolby Atmos.
5. Near the bottom look for "Style preference" under the Earphone adjustment section
6. This will bring up an Equalizer.
7. Turn up the gain !!!

I installed this as well but other than downgrading my viper4android version it didn't do much... In mastergate I put the output to Max but it's still so quiet. I find it embarrassing how a jailbroken iPhone can do this is 2 seconds but with an rooted Android it's impossible?. Where is this Dolby plus? I just have the normal settings.

Check if sound is processing by pressing icon next to settings icon. If not, go to settings/apps and clear viper storage and set up again. Dolby plus is part of a custom rom. Try getting viper to process sound first.

There is a change that is clear. Yea I know... I installed the custom rom m
So is there any solution to this? I also noticed that my bluetooth volume is way more silent now, even if I go up with the volume.
