Hello Robert!
 
I want to do the same thing as you. The methods for redirecting audio according to the different HOWTO:s seems to involve A2D2P which, I think, is used for point-to-point communication with a headset. A2D2P is not SCO, but rather ACL (am I right)?
 
I would like to receive SCO and redirect it to the sound card via Alsa. The idea is that I will recieve SCO in a buffer and then write the buffer to the sound card with Alsa functions. The sound card must be initalized with the correct parameters regarding sample rate, PCM format and so on before beginning to write to the buffer.
 
I will also record voice via the sound card and then write to a buffer to the socket for SCO.
 
We have a test version where the voice from a Bluetooth client is echoed back from the master to the client. The result is that the person talking in the headset will here himself. This is simply done by reading the SCO socket and writing back the same data to the socket.
