  Hi
   
  Thank you very much for your comments. I was wrong. I've already seen the A2DP's implementation over ACL channels in the page bluetooth-alsa.sf.net.
   
  On the other hand, I'd like to know if you had studied the Video Distribution Profile (VDP). At first, my objetives were to develop the A2DP or, if it was already implemented, the VDP. Therefore, I'm interested in knowing if you have implemented something similar to a2play for A2DP.
   
  Regards.
  Javier
