I don't have a

I don't have an adb folder in /data. I think that must be an Android 10/11 thing. My issue is on my Android 9 rom.

The problem has to be with the latest Magisk update..
No, I have the /data/adb folder on my oreo device, running the latesst stable. NB: /data/adb is a standard android thing even before you install magisk. /data/adb/magisk (and a few others) is a magisk thing.

Hi guys, for information, i'm on Poco F1 Arrow OS v10 (Android 10) with Magisk 21.2 + V4A 2.7.2.1 and work fine.
Tested on Miui 12 and RR (both Android 10) works fine too.
On Mi9T Pro Bliss Rom Android 10 works fine too.
Thanks.

Since the latest Magisk update this stopped working for me.. I reinstalled the newest version a bunch of times and it just won't start. I can only think of the Magisk update, nothing else changed within this phone.

I really hate how Viper4android is the most valuable app I have and the one that can suddenly just stop working. I guess I will get this damn thing to work some days later.
Yes, V4A is valuable for me too.
You tryed flash kernel separated from zackptg5 or Audio Compatible Patch or Selinux Permisseve or downgrade from Magisk...

Good luck.

I dont know how or when I found it, but I used this zip in magisk, on my pixel 4a running Android 11. I am sure I must of got it somewhere off here, but when I search for it, I cant find it to give attribution to who posted it first.

ViperFX_Android11.zip

The only thing I changed (because I can) is that I switched it to boot SELinux Enforcing and it still works. The existing ZIP forces it to boot permissive
Thanks to you for providing this module and thanks to the original author, whoever that may be :) It works perfectly on a Pixel 5 with Magisk 21.2. No need to install drivers after first launch and then reboot again, it instantly works! And the best: it is Viper4Android v.2.7.1.6, so the old UI with the different output sources in the bottom bar and imho better UX than v2.7.2.1.

Turning SE Linux permissive worked.

Now Legacy Mode works.

Another one here that updated Magisk and lost V4A.

If I check Legacy Mode it mutes for 2 seconds then sound come back with no changes.

Someone with better knowledge should look into this issue so we don't keep guessing and messing with our phones!

Hello everyone!

I have viper working on my Android 11 Pixel 2XL (custom rom). However, I notice that my newest Sony bluetooth speaker shows "abnormal" on it. This has a new option in the bluetooth settings: "HDaudio:LDAC". Is there any work on an update to Viper for newer devices and features?

It comes from here maybe...

v4a 2.7.2.1

Is there any fix for v4a not processing on youtube in normal mode (not legacy mode)? v4a works fine with music players except youtube. I have installed ACP and AML.

I have no problem in legacy mode, all is fine (youtube, music player, video player), but battery draining fast.

Version 2.7.1.6 works with youtube & others on my 4a Android 10 stock rom.
Stay with older version until they get the bugs out

I just wanted to report that since I installed this module on a Pixel 3 XL running stock Android 11 I have experienced the following issues recurrently:

- Android Auto not launching when plugged in my car.
- WhatsApp freezing after video call ends.
- Bad microphone sound reported by my callers via WhatsApp video calls.
- Random freezes and unresponsive power button.

After uninstalling the module everything is back to normal.

I am the only one experiencing these?

Good :) You can use playback gain control as well.
I do feel it's a bit louder cause OPT is at 0.0db now(which was -1.9)
Still it's nowhere near what my stock rom offered. I did make a clean install of V4A.

Q1) Anything else I can do?

Q2) Some convolvers like Dolby pro logic and Zloud seems to make the sound louder but they aren't good and makes the sound buggy. Can you suggest some convolvers that will bump up the sound without making it buggy?

You can increase output gain under "Master limiter" section too.

I used to use Dolby Pro Logic convolver and it gave me no disturbance at all... Now I don't use any convolver, so I don't know
