Hey buddy:

 Yes, i'm using a minikit without a motherboard(I don't have a ST
motherboard in hand : ( ). I connect the minikit to my CPU on the
development board with both UART and PCM interface.The version of the
chip is STLC2500C R4.2. I also have ssf file (which can be loaded into
the chip with certain settings)configured with the pcm settings.Please
see the attached file.
 I'll check out my ssf file settings to make sure there's nothing
wrong with my pcm interface settings according to the spec of my
CPU/STLC2500C.Other than that , i have no idea why there's no sound
coming out of the bluetooth headset.....

Thanks!!
