I want to do the same thing as you. The methods for redirecting audio accor= ding to the different HOWTO:s seems to involve A2D2P which, I think, is use= d for point-to-point communication with a headset. A2D2P is not SCO, but ra= ther 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 w= ith the correct parameters regarding sample rate, PCM format and so on befo= re beginning to write to the buffer.
 
I will also record voice via the sound card and then write to a buffer to t= he socket for SCO.
 
We have a test version where the voice from a Bluetooth client is echoed ba= ck 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 socke= t and writing back the same data to the socket.
