Hello all,
I am trying the new bluetooth-alsa plugin as mentioned https://help.ubuntu.com/community/BluetoothAudio.
All goes fine but while playing a file via "aplay" i get absolutely no sound output.The previous way of a btsco kernel module worked out of the box.
any pointers ???. ..
herez the output:
1. output of headsetd -n
headsetd[267]: Bluetooth headset daemon version 0.42

be in a new cvs module.
