Since the output is set to auto in the mms I have some other problems. I no longer have to kill esd to play ac3 (because it isn't used anymore ;)) but watching videos the sound gets async after awhile and like I said before I can only play one sound at a time. The latter seems to be a kernel driver problem - the first - don't know.
