There are a lot of topics about this but none of them helps .
when i try to change profile of my headphones to a2dp
it gives me following error on blueman .
Before i was able to connect only disconnecting after initial connection and connecting back through the buttons on my headphones but it doesn't work anymore.
when i try to load bluetooth discover module using the command pactl load-module module-bluetooth-discover
i get Failure: Module initialization failed
error.
At the moment i can only connect to hsp/hfp profile which results sounds from star trek
