what do you mean set the IEC958 status bits? who sets it? atiixp.c? my board is a gigabyte GA-8TRS300M with ATIIXP/ALC655 and i test by running aplay with a wav file and ac3dec with an ac3 file. with alsa-cvs using bith aplay and ac3dec, software says it is playing but i get no sound, the optical spdif light is not lit. with realtek-alsa-1.0.4, the software says it is playing, still no sound but the optical spdif light is on. i am loading the atiixp module without options, just defaults. alex ------------------------------------------------------- This SF.Net email is sponsored by: Oracle 10g Get certified on the hottest thing ever to hit the market...
