Hi Katja This is a pretty basic device with just hw0:0 for capture and playback, but I will double check the mixer settings.
Someone from Freescale has been in touch and it looks like either a driver issue (fixable) or errata on the board (not fixable). I might try a USB audio device. Anyone know what ones work with ARM?
