No a2dp with bluetooth headphones

suse_paul · March 4, 2025, 5:54pm

I can not connect bluetooth headphones to OS 15.6 with A2DP. they only connect as HFP with corresponding bad quality with interruptions.
if I select A2DP in pavucontrol then the sound disapears and the headset disapears from the list.

A second headset does either not connect, or pretends to connect but doen’t show in pavucontrol.

both headsets worked fine on the same laptop with OS 15.5.

how can I connect the headsets via A2DP?

sudo systemctl restart bluetooth

made it for the first headphones but the second still doesn’t show

ps:
I forgot how to insert the list properly. If I use double backticks it looks messy.

Can you run:

> bluetoothctl
# devices
# info <mac-address>

With <mac-adress> being the MAC address for the headphone you have problems with.

For my working BT headphone that gives:

Sorry, I make a type, not show <mac-address> but info <mac-address>

As you see your paste is not that readable, somehow the new-lines are missing.

suse_paul · March 4, 2025, 8:30pm

I did one more factory reset of the headphones.
then I connected them twice: while they where in the case and when they were taken out.
Now they work!
They are twice in the bluuetooth list with different names but the same MAC address, and once in the pulseaudio list.

suse_paul · March 6, 2025, 3:48pm

after setting up a new installation of OS 15.6 I encounter problems again.

I can connect two headsets via bluetooth. they connect properly with A2DP.
Although one is showing twice in the list od bluetooth devices…

the third one is behaving strange.
It shows as connected in the bluetooth list. under changing name.
but it does not show in audio devices.

what can I do to properly connect the headset?
