I have already achieved the alsa-driver which can playback and capture function with two channel.
My board based on ARM9 which have 3 ADC & 1 DAC in IIS bus and all of them shared the same BCLK and LRCK. The pins figure Like this:
| BCLK |___________
| LRCK |___________
| ADCDAT0 |___________
| ADCDAT1 |___________
| ADCDAT2 |___________
| DACDATA |___________
Every ADCDATn(n=0,1,2) has two channel so the question is how can I get multi-channel audio data such as 4 or 6 in capture funciton?
