[ New Update 2 ] – Viper4Android Not Processing At All on Latest Custom ROM and Android 12.

So I have met a few encounters where Viper4Android does not process at all because there is more than one Audio Effects System installed on Android System.

In my case, I had Xiaomi Parts Audio Effects Control and installed Viper4Android FX as well. So the processing of audio gets conflicted and unable to process to which Audio Effects the Audio should route through in System. That is why you have to patch the library.

AML’s job is to process different audio mods simultaneously but recently I have installed Android 12 and does not properly. Here is when the Audio Compatibility Patch Magisk Module (ACP) Comes into play. With this module, you can patch Audio Policy, AUdio DAC, Patch Audio Effects, and patch & install LIB Workaround.

I have already shown this method in my YouTube Video that is below, check that out as well. I had published the video when this problem started occurring at the beginning. You can also check that video to get more detailed instructions and guides.

I have embedded John-Fawkes Module. But it’s recommended to download the module from Magisk Manager App.

[New Update 3 – 2022] – Viper4Android Not Processing on Wireless earphone or headphone devices.

So recently I came to know why Viper4AndroidFx does not process on Wireless Earbuds, Neckband, and Headphones. The reason for not processing viper4android is sample bitrate limitation through Bluetooth.

Viper can only process audio up to 48000KHZ audio sampling bitrate only. Beyond the 48000KHZ sampling rate, it will not process the audio.

If you have LDAC Audio Codec available for wireless devices which support up to 96000KHZ Sampling rate then Viper will not process the audio. You have to use AAC Codec which is captive to 44100KHZ Sampling rate and then audio will get processed 48000KHZ.

I own Realme Wireless 2 Wireless Neckband and it has support for LDAC and that is why Viper4Android was not processing the audio.

If you are using Wired Earphones or Headphones even so it will process maximum at 48000KHZ Sampling rate.

Sometimes Viper4Android struggles to process audio from YouTube but works fine with other Audio Players including Spotify. So it is one thing that needs to keep in mind.

How to Fix Viper4Android Not working and Not processing in Android 12 and Custom ROMs

Now let’s follow the process of how to install and patch the Audio Effects in Android 12 and Custom ROMs using Audio Compatibility Patch.

Step 1: Open Magisk Manager.

Step 2: Head on to the Modules section inside Magisk Manager.

Step 3: Click on the Search in Modules section and Type Audio. You should see Audio Compatibility Patch Module on the third or fourth number.

Step 4: Click on the Download icon of the Audio Compatibility Patch Module then select and click on Install and your installation should get started. ( Make sure Internet connection is available )

Step 5: While Installation you would have to use Volume Keys or buttons to select the settings. The Settings are given below:

  • Press Volume Down ( NO ) for 1st prompt to patch Audio policy ( deep buffer removal ) which comes in handy if you have cracked audio sound.
  • Press Volume Down ( NO ) for 2nd prompt as well to remove the notification helper. This comes in handy if your audio profiles for Music, Call, Alarm, and Notification sound are mixed up which gives you cracked audio sound.
  • Press Volume Up ( YES ) for 3rd prompt which patches USB Policy for USB DACs. You could also choose Volume Down ( NO ) if you don’t want to patch USB DAC but I did on my Android 12.
  • [ IMPORTANT! ] Press Volume Up ( YES ) for 4th prompt to use Lib Workaround which adds Audio Effects Library Workaround to route audio to correct Audio FX Mod.

So the pattern for the ACP setting is NO NO YES YES.

acp settings

FACT: Well you could use Yes or Volume Up on all the prompts except for Notification Helper Prompt because that patches Cracked Audio Sound which you might not need and might cause some issue on your Android device.

[ NOTE: You have to be very quick while the installation otherwise the installation will fail or you will miss the suitable settings. If you miss any settings then you have to delete the Module and Restart installation again ]

Additional Step for Viper4Android Not Working or Processing on Android 12 or Custom ROMs

Some users suggest that if you don’t have the BusyBox library installed then your ROM will not process Audio Effects because ROM audio drivers for C++ or C+ applications aren’t available by default which needs to work to process Audio Effects or Audio Mods like VIper4Android FX.

I don’t know how much this is true but installing BusyBox Applets as well might help fix the issue of Viper4Android Not Working or Not Processing in Android. By the way, installing BusyBox doesn’t cost anything so give it a try.

How to install BusyBox in Android 11, Android 10 and Android 12.

To install BusyBox applets is very simple. Follow the steps below:

Step 1: Download & Install BusyBox APK from PlayStore & APKMirror or Download BusyBox Magisk Module

Step 2: After installing BusyBox, Select the location where you want to install. Normally /system/xbin or you could also install in /system/bin if you want then the custom path is also available but I wouldn’t recommend because /system/xbin is the default location.
