We could not find the data sheets for the chipset. If someone could direct us to the data sheets of cm8738 it will be great else one doubt that we have about the card is - when exactly does the card raise the interrupt in playback mode. Is it after physically playing out and thus finishing the period_size number of frames or is it after the period_size number of frames are copied into the hw buffers(?) of the card? Exactly at what point does the cm8738 card raise an interrupt? --Shaju Abraham ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf
