Javier,
 
I think that you did not read the page bluetooth-alsa.sf.net completely.
Both SCO and ACL implementations have been done.
Maybe you can add some new feature to the existing A2DP. (a2play = or pcm_a2dp).
I think support for the mp3 codec (making a choice at run time between= SBC and MP3 codec) could be handy.
Also, the A2DP spec mentions briefly about RTP. Nobody has looked into= that till now.
 
Regards
Mayank

Hi,
I'= ve visited bluetooth-alsa.sf.net<= /a> and the project is very interesting but I think that the profile's impleme= ntation is based on SCO channels. If I'm making a mistake I apologize for i= t. On the other hand, I've read the A2DP profile specification and I think = that an implementation should uses ACL channels: "The Advanced Audio D= istribution Profile (A2DP) defines the protocols and procedures that realiz= e distribution of audio content of high-quality in mono or stereo on ACL ch= annels (Introduction of Advanced Audio Distribution Profile Specification)&= quot; So I'd like to develop an implementation using ACL channels instead o= f SCO channels.

I'd like to know if you're interested in include this implementatio= n in the BlueZ stack too. 
Thanks.

Javier.
