So a pandemic is upon us and it's remote working season again.
I have bluetooth earbuds (Sony WF-100XM3, think high-end airpods) that I succesfully connected to my laptop running Arch - a Dell XPS 7590 with a combined bluetooth+wifi Intel wireless card.
I've fixed a bunch of issues already - namely, sound being too low, easily switching between A2DP and HSP for visioconference, play/pause buttons on the headset not working... If you found this thread through a search engine and have any of these issues feel free to send me an email.
Now for the last problem I can't figure out: Sometimes, while in A2DP profile, the sound just cuts off. I have to reconnect the device via bluetooth and it automatically starts working again.
This happens seemingly at random.
I get the following in journald output when the sound cuts:
