Nothing costs you to try the second I listed - somebody else reported it worked for his Poco (maybe diff model than yours, but who knows)

I tried today, its not possible because I have discovered that my system is EOFS :/

I no longer have the 10 pro as I switched to another device. I think I remember installing AML, jamesDSP, and the following dolby atmos to get jamesDSP working:

Thank you for the guide.
Working on Realme GT2 Pro - Realme UI 3.0 11_A.19

Following the order,
1. AML
2. JamesDSP 4.6 (Chose the Huawei route, tired playing around the combination)
3. Dolby Atmos revision
4. Reboot

Probably tried almost all the methods for Viper and nothing works.

So I'm not sure if I'm doing this the right way, but I think in an effort to get experienced devs to take a look into our viper4android driver loop issue a bounty is in order.

I have tried every method I could find to get viper4android to work on our OnePlus 10 pro with no success.

Below I'll start a list of pledgers who are willing to pay the bounty when/if a fix is found. I'll add to the list as other pledgers come forward. Any pledge amount helps.

Unfortunately, Issues cannot be reported to GitHub for that project:

But I got in contact with the dev by Telegram...

Now, his Viper4AndroidRepackaged is updated on the GitHub and it searches for additional folders on /vendor with audio_effects conf and xml files to properly patch them

It works excellent on my Xiaomi (A12), I don't need to add the post-fs-data.sh script anymore to mount the patched conf and xml files

try this:
remove all sound mods you have added, including the module from magisk and the viper app!
reboot!

Install attached Audio-Modification-Library_v4_0-OS12-op10
reboot!
install com.pittvandewitt.viperfx_2.7.2.1-2721.apk
open the viper app, and click install drivers.
phone auto reboot.

copy attached post-fs-data.sh to /data/adb/modules/ViPER4AndroidFX/ (use adb or rooted file manager)

REBOOT, do not open the app!!!!

now if we hit the FIX, if you will open the app it's should not ask to install drivers.

if it's stop asking, check the state, if it's not NORMAL then tick the Legacy Mode, and check state.
should be Status Normal.

I hope this will work for you.

Thanks to the programminghoch10 dev, and @dladz for pointing here earlier about his GitHub project

thanks, I have tried but again, this version patch audio_effects.xml correctly but I still have driver bootloop. I think it's because I have the EROFS system.

I don't understand what would be the catch with your EROFS.
But your problem is maybe in the missing 64-bit audio drivers/lib in V4A

All of us have read-only system (on all the new devices)

That is what for the systemless rooting by Magisk and the systemless modules serve for - they mount changes on every reboot, they do not do any hard change on the system

However, JamesDSP requires to use Huawei mode on Huawei phones (and some other devices) and that option does actually nothing else but forcing to install the 64-bit libjamesdsp.so

And that option is missing in V4A (it installs only the 32-bit libv4a_fx.so). That could be the problem on your Huawei (is it Huawei), or other device(s) using 64-bit audio libs

You could reach the dev of this V4A Repackaged module by Telegram and ask him if he could add the 64-bit V4A audio driver - TG, he seems to be willing to update V4A for the new devices

Thank you very much for answering. In the JamesDSP forums the dev told me that V4A is most likely missing that 64bit library, in JamesDSP the Huawei option is 64bit and the other 32. Another person told me to install the magisk delta since (literally ) "EROFS need an early init to modify it's system", I think the first option is the right one since the second is somewhat riskier.

My mobile is a Pocophone f4 gt (Xiaomi) but I know that the problem is repeated with Oneplus 10 pro since it uses the same file system.

Systemless mounting works the same way for all modules - does eg AdAway with Systemless hosts work on your device - if it does, then the same mounting must work for V4A

Also, use any root file explorer and go to /vendor/etc, open (as text files) audio_effects.xml and audio_effects.conf and compare against my screenshots

If you see the v4a patches inside - then patches are mounted and there should be no problem related to EROFS
