actually the endpoints of the first two pcm streams are identical. is the sound only mono? on the description, it's defined as stereo streams. so i guess quattro has two stereo streams, corresponding #0 (or #1) and #2. it seems that the stream #0 has only 16bit 44.1kHz at most, while the stream #1 supports 16/24bit 48kHz (although 24bit-3bytes format is not supported on alsa yet). > > i committed a minor change to cvs. > > now endpoints will be shown in each proc file. > > could you apply and send me the output of each proc file? > > i'd like to know whether really endpoints are parsed correctly. > > > > > > From the looks of things they are not. well, it looks ok. the stream corresponds correctly to the description. > > > > >>I have also tested capture and the card is not working with that yet. > >> > >>It will attempt to record for a few seconds but will not write to a file > >>or produce any noise either with direct monitoring enabled or not.
