Running on WSL cause the windows verision didnt even show anything after saying playing Audio.

Android: 10

Adb Version:41

[rom1v]

It seems that your VLC fails to run from there. Try vlc some_file.mkv from WSL.

VLC works and starts playing the video file, but it cant seem to output audio, i am working on a workaround cause WSL doesnt natively support audio output.
