[V4A] Fix for 'Processing: No' while using Magisk

[DiamondJohn]

The only thing that works for me is setting Selinux as permissive!

If you log what is explicitly being denied by SELinux, you could add specific allow's within Magisk, to enable it working under enforcing.

I'm running RR rom and they have a AudioFX app from LineageOS. Went into the app and disabled it, then everything started to work for V4A

viper4androidfx processing = no (fix)

first I uninstalled stock audiofx.
i have the same problem where sometimes processing=yes and sometimes processing =no . my device is moto gs5+ (stock moto rom Android 8.1). i tried the above solutions the problem arises is that I can't delete or modify system files (for example audio_effects.conf) because my partition is read only .

”solution I find out” = goto system/etc/audio_effects.conf moved the /magisk/v4a/system/etc/audio_effects.conf open this file with text editor and select all , copy it

then goto

system/vendor/etc/audio_effects.conf open this audio_effects.conf delete or erase all the commands and paste here save it and reboot

now viper4androidfx work flawlessly in every all app with processing=yes when ever there is audio playing
hope this solution help someone.

For me installing Audio Modification Library in Magisk turned out to be a solution

 

[mahin.kk2]

yeah but im not able to find it "/magisk/v4a/system/etc/audio_effects.conf" is it located in the root directory.. In my freedom rom i can find only magisk folder with some arise sound config files, no v4A folder.

if you using AUDIO MODIFICATION LIBRARY (AML) you may have to go to data/magisk/AML/v4a/
and you can find those files

 

[Alnashief99]

just follow this

1. install terminux in google play
terminux link
2. type "su" then press enter
3. type "setenforce 0" press enter
4. play any song and try to check it again

Hello guys! I am with my OP3T and android 9 stock 9.0.6. I am root with magisk 20.4 and when I install the V4A it won't let me use it, I have the problem mentioned in the post. I have SOLID PRO installed but I don't see the path /magisk/v4a/system/etc/audio_effects.conf to be able to copy and paste the file, in which folder is it?
Thanks cracks!

For v2.7.1.0
I think you are looking for files that would be under /data/adb/modules/ViPER4AndroidFX. But if its there, then magisk will mount it where it is destined to be.

Thanks friend for answering.
It turns out that the path / magisk / v4a I don't see, so I went directly to the path SYSTEM / ETC ..... and there was the file in question, but I copy or cut it and overwrite it in the destination path and nothing, remains the same in PROCESS: NO.
I have also done something else that a colleague said to replace a file with .sh extension by .bak, and it has not worked for me either because when I restart and open the V4A, it asks me to install the driver again, so it did not help me.

Can somebody help me? is that my OP3T is very weak, only on calls, if I put videos and others, it is perfectly heard.

Someone could put the steps from 0, I want to do it from 0 and delete everything that doesn't work for me.

Thanks cracks!

Is this advice still current?

Will replacing it with a hard link work too?

 

[DiamondJohn]

Is this advice still current?

This thread is FULL of advice, which part in particular are you referring to?

Will replacing it with a hard link work too?

A hard link cannot cross partitions. ie you cannot do a hard link from data to system, so it would already need to be on system to hard link it to the system partition. This is what the Magisk module enables. EDIT: To be clear, Magisk mounts from the data partition, onto the system partition, not a hard link.

Assuming you have a root explorer... Check in /data/adb/modules/ViPER4AndroidFX/vendor/etc or look in /data/adb/modules/ViPER4AndroidFX/system/etc and edit it there. Reboot afterwards.

Viper4android driver not enabled
Android 8.1 installed viper4android legacy

 

[DiamondJohn]

Solution

The only thing that works for me is setting Selinux as permissive!

If you look at your logcat, you can determine which selinux policies are being violated, and "punch a hole" specific for those, and then you should be able to run enforcing.

Disclaimer:
• First, you have to follow the basic rules of V4A such as no other audio mods (AudioFX, MusicFX,...), uncheck direct control volume in Poweramp...
• Since Oreo, I only flash this Magisk module and I no longer have to follow the below steps.


1. THE PROBLEM

• You are using ViPER4Android app and the V4A module from the official repo of Magisk.
• Driver is installed, V4A is enabled but Processing is stuck at NO!

2. THE SOLUTION

• Move /magisk/v4a/system/etc/audio_effects.conf to /magisk/v4a/system/vendor/etc/audio_effects.conf (check the permissions).
Note : overwrite the existing file or add the extension .bak
• Reboot.

Now start your music app and check the driver status screen of V4A. You should have this:

Enjoy

I found this solution in one of Magisk threads. Hope it will help other OP3T users.

Still working in 2024 with a android headunit. Even stands after reboot.
