Try this! 1) Pair the headset and run pavucontrol the pulse audio volume control panel. 2) Go to configuration 3) Change to off 4) Change to a2dp

When I connect my bluetooth headphone, sometimes I can activate the A2DP mode (which gives a good sound quality) and sometimes I can't (nothing happened when I change it in the configuration window), and I need to switch to HFS/HFP (bad sound quality). Note that some logs are attached. I found on the internet a work around which is to put in /etc/bluetooth/audio.conf a line Disable=Socket It seems to work (well it's hard to say for the moment because I didn't have the time to do much tests), but I would like to know what Socket is supposed to do. Would it be possible to solve this bug when Socket is activated too ? Thank you, Tobias.
