For the ALSA sound card, this is basically what snd-bt-sco does. The issue with this alternative, is that the headset&handsfree profile mandates the use of an RFCOMM channel before to use SCO. Doing this at kernel level will mean that SCO layer will be dependant on RFCOMM sockets, or that user space will have to handle RFCOMM channel before to open ALSA device. This is roughly the way btsco works today.

It is coming back for sure. Ok, i will stick with mh1 then....
