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
