This should be working assuming BlueZ is configured properly. You might need to configure BlueZ's audio.conf with: Enable=Media,Headset,Gateway,Sink,Source This might not be necessary if your BlueZ is patched which is probably the case. Another possible issue is that you never connected the profiles. You can try by calling the D-Bus AudioSource.Connect() (for A2DP) or HandsfreeGateway.Connect() (for HFP). This is likely if the phone didn't initiate the connection automatically after pairing. You can also play around by manually initiating the connection on the phone's UI. Note that Audio.Connect() does not connect these profiles, which can be misleading. Cheers, Mikel
