Playback Issues

[ghost]

Playback on Firefox and mpv are way too slow (can't even play 720p without dropping frames, but on Void Linux Musl does 1440p 60FPS no dropping) and I can't get the audio working (already installed the packages and built-in kernel support).

This sounds to me like a kernel issue though I cannot be sure. I cannot reproduce your issue here.
