But I assume the plug handling does not do any SRC if it can avoid it by adjusting the hardware? > For HDA , it support multiple streamming. some HDA codecs (e.g. alc88x and > ad198x) have 3 ADC ( which you can capture three stereo streams concurrently > from internal mic, external mic and line in ) > > The main problem of the recording audio application is unable to select the > correct mixer control of the three capture sources What I would like would my enumeration function to return in this case would be four entries, one for each ADC and one for them all combined (6 channels, multi-channel recording). // David _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
