hey,
Flashed V4A , but it doesnt open. It FCs. I'm on Lenovo K4 note RR OS 5.8.3 and Magisk v13.1(Stable). Removed all other mods (Dolby, AM3D, even AudioModLib), but no help. :(

Have you tried this:

Until the module is updated that's a possible workaround (works for me).

If you're using the module from this thread you should not remove Audmodlib. It's what makes it tick...

Thank you.
Works well with Magisk 13.1 and Moto x pure LineageOS 14.1

What I did.
a) Install Magisk 13.1
b) selinux android app and set it to permissive
c) Install v4afx_v1.4.zip

Thank you once again. Its a blast to finally have some good audio :)

How did you managed to get permissions changed? I tried several ways and could not change /magisk/.core/service.d/audmodlib.sh permissions to 755 :(

Most root capable file explorers could do that, or in a terminal emulator:
Code:
su
chmod 755 /magisk/.core/service.d/audmodlib.sh

Oddly enough on my V20, I'm good for one round of music before it won't process. After reboot, I can play music through headset, BT or speaker no problem. If I disconnect BT (i.e. my wireless headset or radio), no longer processes to any output until I reboot. Running Magisk v13 and this Viper module. Did the seinject modifications, build.prop changes and permission changes.

I can do the terminal emulator change permissions.....anyone please direct me where to find the spot and how to do the injection part please? I have searched and searched and am sure it is right under my nose but I just can't find it.

    Deprecated - Use the New ViPER4Android v2.7:
    GO TO THE THREAD LINKED ABOVE. You don't need to flash any zips. Just install it as a regular apk, allow it to install the drivers, and you're good to go.
    For magisk users: I made a zip on the repo that includes the original vdc's and my profile converter (will convert your old profiles to the new and better format).
    For rootless users: I made a zip to install drivers and such
    Zips can be found here
    ALL SUPPORT QUESTIONS FOR 2.7 SHOULD BE AT THE THREAD ABOVE.

    This is ViPER4Android FX and Xhifi Unity installers

    These installers utilize my Unified installer that can install on Magisk OR System if Magisk is not detected (with Pixel support).

    Credits of Originality:

    Special Instructions:
    • If you already know which original v4a you want to use, just add 'old' for 2.3.4.0, 'mid' for 2.4.0.1, 'new' for 2.5.0.5, or 'mat' for material to the zipname prior to flashing.
    • If you already know if you want it installed as a user or system app, add "uapp" for user app or "sapp" to system app to zipname.
    • If you already know if you want to apply the libstdc++.so lib workaround, add "lib" or "nlib" to zipname (note that there are some devices that are already known to require it and so they'll apply workaround regardless of choice)
    • If you already know if your device/rom requires the v4a open/close/fc audioserver workaround, add "ocw" to zipname. Otherwise, add "nocw" to zipname
    • To skip volkeys (if your device isn't compatible with them), add "novk" to the zipname. Note that if you don't specify the above, defaults will be applied which are: sapp, new
    • Make sure there are no spaces in the zipname

    Been busy with my new mod specific stuff and then work. The problem is that I have to update like 13ish update binaries because this new Magisk changed quite a bit. Usually I just do batch editing which allows me to make changes in minutes. This will take like a good days worth of work for one of my days off.

    It's not just for this mod though. Thank you for your patience.
