Hi Pierre,

Thanks for yor quick response. You are right the MIC connected is Analog. Basically we have back ported the SOF Audio changes from kernel 4.14.69 to Linux version 4.14.48. We had to modify the number of channels to 2 to make the stereo playback work on the dirana interface. Please see the changes below

Hi ,

   I am trying to add MIC as an record device in the SOF firmware on the Apollo lake MRB platform.

   Is this supported by the SOF architecture already?

To the best of my knowledge, only analog microphones connected to the Dirana chip can be used on this platform. The microphones would thus appear as a set of slots on the TDM link, and that configuration is supported by the SSP code as long as you have a matching setup on Dirana and APL. Would you mind sharing which versions/SHA1s you are currently using for Linux driver and firmware to help confirm my answer?

Thanks
