I have a working sound support for the mx31moboard boards available here:
http://github.com/retornaz/linux/commits/moboard-sound

It's basically Sascha mc13783 codec driver (from his git tree) rebased on 3.2 
and some mx31moboad specific code.

I can playback & record sound on our board (2 channels at 16Khz) with the sdma.

Sascha, do you have any plan to upstream the mc13783 codec driver ? 

Thanks,

Philippe
