I have an issue on Ubuntu 20.04.6 LTS where the the audio on my HP Omen laptop cuts out for ~1 second at a time, usually shortly after going from "no audio playing" -> "some audio playing", see this video I recorded. Prolonged continuous audio (e.g. youtube video) is fine.
This issue occurs across applications (vlc, chrome, firefox, system sounds test) and audio sources (music, video calls, videos) but appears to only happen for the laptops main speakers. Audio through bluetooth headphones and the dedicated audio jack appears to be fine (I'm 100% sure this was a problem through BT headphones as well, but can't reproduce it right now...).
I have tried all the solutions from this post, as well as the posts it links to in the description, but none of them have helped.
Some logs from running a video through VLC (captured between un-pausing and re-pausing a video):

There is no output from dmesg during the playback from vlc (other than audit messages).
