[SOLVED] Bluetooth audio A2DP stopped working after today's upgrade

Hi!

After a long time with no issues, I found my headphones stopped working. Tried the usual remedy of downgrading to older bluez, but to no avail. HSP works fine.

Any idea/known bugs before I invest more time into the issue?

With bluez 5.75:

I also saw some other messages that I can no longer reproduce:

Ok, fiddle with that a little more and noticed when I switch to A2DP, something mutes the headphones. Unmuting them fixed that and the fix seems to be permanent. No idea what happened in the first place though.
