Hello there.
I've been trying to get Viper4Android to work and tried the most common solutions (none worked yet)
-> manually edit /data/adb/modules/ViPER4AndroidFX/post-fs-data.sh didn't work
-> using the automatic editing via magisk module didn't work
-> trying to use JamesDSP/audio compatibility library in between reboots installed/deinstalled didn't work
I also tried the "newest" fix version from the v4a Telegram group.
Any time I use a pair of bluetooth headsets, the options menu just states "abnormal" and v4a doesn't work.
Strangely enough, if I use the phone speakers and have NO bluetooth headset enabled, the processing works normally.
Anyone found a solution yet?
I plan to use this thread as a discussion first and once we found a viable solution that can be reproduced, I will edit this post to a guide. In the following spoiler I'll progressively add more information that will later replace the main text.

Official v4a XDA Thread
1. Purpose
This guide serves as an installation method to get Android4Viper working on a Google Pixel 6 Pro (as of 12/2021). If not stated explicitly otherwise, do not assume that this method will work on another Android 12 device.
2. Installation method
3. Download
Viper4Android cannot be downloaded via xdalabs anymore. The installer (old 2020 version) can be either found here https://zackptg5.com/android.php#viper or as a magisk module in the new unofficial repo via Fox's Magisk Manager Module https://github.com/Fox2Code/FoxMagiskModuleManager (John abandonded the official Magisk Repo as of 12/2021).
4. Now that I have Viper4Android running... where do I find the right settings for my specific pair of headphones?
For a baseline, you can visit the GitHub page of the project AutoEQ and find the settings that fit your need https://github.com/jaakkopasanen/AutoEq/tree/master/results/crinacle
There is a general thread for Viper4Android profiles that are being shared by the community (sometimes with attached DDC & Convolver files) https://xdaforums.com/t/read-op-first-official-viper4android-audio-profiles.2324454/
For a generic IRS file ("DDC") you can visit this website https://github.com/Codejune/viper4android-eq/tree/master/Kernel
If you want a specific DDC file tailored to your headphone, there are several XDA threads to chose from, where members of this community take the time and effort it takes to create those - usually these files are sold, you can expect about ~ 3€ per headphone IRS file pack. There are some floating around github or other parts of the net, but those are not always "official" and might have been shared without consent of the original creator. One creator of these files that offers them for free can be found here https://xdaforums.com/t/v4a-irs-ddc...filters-2016-06-05-5-new-hifi-models.2372750/
For a Convolver file you can also search for them in several XDA threads (usually for free, DDC files are usually the ones being sold) - for example:
5. My device bootloops after installing a magisk module (fix)
Most bootloops caused by a magisk module can be solved via safemode boot (automatically disables magisk modules).
