Juergen,
does anybody understand the DAM unit in the i.MX27 processor?
Not that I really understand the AUDMUX unit, but the current Freescale BSP (19 Dec 2007) contains an audio/alsa driver which makes use of the AUDMUX, or DAM, in order to route audio streams to/from the mx27's SSI1 and SSI2 to the PMIC's SSIs. PMIC is a the power management and audio chip which is on the ADS board. Unfortunately I do not have the file with me, it is called ./sound/arm/mxc-pmic-alsa.c I believe.
I will be back in office next week, maybe we can have a chat then, if it is not too late.
Regards, peter
