Thanks for the reply Niels, I do not have any hdmi port on this mobo so that is not the case. I still believe it to be a driver issue (i read on alsa bugtrack that since nvidia apparently hasnt released specs the driver is a "guesswork"). I think that if i could just get the iec958 and spdif ports to use hw:0,0 instead of hw:0,2 everything would be fine, but i have no idea of how to do that. It might be that the S/PDIF pinheader connector on the mobo gets the output, too bad i dont have a connector to test that with, the manual says its only for optical though i suppose coax would work ok as well?
