[New] Viper4Android on Android 10 (No ringtone distortion/bluetooth audio issue)

[harshs91]

Hi there,
The tutorial will show you how to make Viper4Android work on Android 10 and avoid issues like ringtone distortion or no Bluetooth audio.
Please uninstall previous installations of viper or any other audio mod before proceeding to the steps below.

(Updated) Steps:

• Download and install BusyBox for NDK from magisk (Don't Reboot)
• Download and install Viper from magisk and reboot.
• Go to Viper app and install drivers, the device will reboot automatically.
• Download and install Audio Compatibility Patch from magisk and do the following:
  -Skip audio_policy patching - No and remove (old logic)
  -Skip notification_helper - No and remove volume listener library
  -Skip usb policy patching for usb dacs - Yes
  -Last option - No (recommended)
• Reboot and enjoy!

You should have working Viper4Android!

Press the thanks button if I helped!

Not sure about ainur as I only use Viper. You can give the pie fix mentioned in the 1st post a try, see if it works.

Now, if you are facing issues like ringtone distortion or no bluetooth audio, please flash the following:

• For ringtone/notification sound distortion: Flash Notification Remover Helper.
• For no bluetooth audio: Flash Viper Pie Fix v2

Note: After flashing the above fixes, you may be prompted to install drivers by Viper again. You can go ahead and install the drivers again.

Sadly flashing "Flash notification remover helper" does not get rid of the distorted system sounds/alarms.

This was the solution for me, no distortion with alarm and bluetooth is working

Strange. Worked for 2 of my devices. One is K20 Pro, running Evolution X. which rom are you on?

Edit: Notification helper remover has two options. Did you try both? Removing volume listener library worked for me.

Looked into this. The audio compatibility patch is a collection of patches mentioned in the original post.

It has a usb audio related patch and the notification helper remover. Would be easier to just flash notification helper remover.

Not initially, but I did yesterday.
Just removing the volume listener library didn't work. So I removed V4A and started from scratch.
Installed V4A, installed AML, installed the driver, deactivated AML and flashed NHR and removed volume listener library and then installed the driver again :silly: .
Don't know why it's working, but it's working as intended now.
System sounds working, BT working,
even my trouble with some IG stories sounding ok and others being distorted are gone.

Thank you.

Thank you.

I know right, the steps are strange but they work.
Anyway, happy to help!

I have V4A + ACP + AML working on my 9T Pro running Android 10 with no issues whatsoever. Only had to install Viper, disable AML, install Viper driver, enable AML, install Viper driver and that was all.

I've followed the procedures, didn't work.
Tried all the suggested combos in the thread, didn't work.
Tried all sorts of weird combos, none worked either.
Notification and ringtones still crackles when viper works.

Not working here...On pixel experience 10 . I either end up with stuttering audio or no bt at all.

Sadly does not work for me either on Evox.

Just making sure, are you guys following all the steps exactly on a clean install?

Also, the steps have worked for me on Evox (android 10) and ParanoidAndroid, K20 Pro Indian variant.

Did you have to reboot at each step?
