Hi Sascha,

For one of our experiments where our robots need to produce sound, I would need a sound driver for mx31moboard platform.

I have quickly hacked something based on what you had done for pcm037 with the MC13783 codec in some of your first sound patches. I know that this is not ready for mainline and I'm still struggling to debug my code, but I would like to have results quite soon so that my colleague could see what sounds (especially regarding to the volume) our system is capable to produce.

I would like to know if by any chance you have some updates on this code ?

Find the latest version of my code here:

And do you know if your initial mc13783 codec support coupled with mx31 had some limitations ? Our setup is quite straightforward, we have direct connection from the mx31 to the mc13783 on a single SSI.

Our board uses both SSI channels of the MC13783 which we then mux into one channel in the DAM unit. I don't know how this affects you.
