Re: No Sound via Bluetooth audio source
Blueman is not at all intuitive, you often have to help it.
Connect your phone
Click on the icon and open devices, you should see the phone.
Start playing some music on the phone
Right click on your phone in devices and select audio source. If successful you should hear music
If not, open up pavucontrol (install it if you haven't got it) and check your input/output settings.
Also have a look at alsamixer, just to check that everything is unmuted
The best things in life are free, so what are we paying for?
