BuzzPCSOS I'm using an HP All-in-One - 22-df0023w, as for where the issue occurs regarding audio, it happens for any and all sources of audio, whether that be watching videos in the browser (both chrome and firefox), playing music through Rhythmbox, or watching any video content through VLC, having tested a bit more extensively I can say the issues are far more prevalent when connected over bluetooth rather than wired
As for drivers, nothing can be found
(I have no function keys capable of adjusting brightness on my keyboard, only the usual media controls and what not)
