Apart from review given for each and every patch (although most issues are shared so there is not as much to address) my question is:
- are these hw limitations or software (machine board) limitations?
The limitation comes from board. Bdw-rt5677 and Broadwell are using I2S with 2 microphones while Bdw-rt5650 is using PCM TDM with 4 microphones. Our DSP supports stereo playback and 2 or 4-channel capture (haswell/sst-haswell-pcm.c).
