Hi Pierre, that's right, i meant a new compress sink which accepts all
compressed formats
data and send to DSP by the new compress APIs.

i remember you said that in previous mail. :)
So what's your plan to support that in pulseaudio part?
for test purpose only, in kernel layer, i wrote a DSP driver as
backend of the compress Api for medfield, also i wrote some test case
in pulseaudio part, they're all proof of concepts and donot test yet.
Pierre, would you share me some idea on that before i can catch up
with you? :)

Mp3 formats has conflicts during transfer through ALSA, i think it's a
solution if we send MP3 data to the new compress sink in pulseuaido.
