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

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

-Pierre
