The motherboard is MSI K7N2GM2, and SPDIF passthrough works fine on Windows XP with stock realtek drivers. On Linux, I'm using the latest ALSA CVS (29.04.2005.) on a 2.6.10-ac12 kernel. I've been able to make a 2 channel pre-decoded SPDIF output work by using the hw:0,2 device. If I use the default device, there is no sound on SPDIF, regardless of the SPDIF related controls in mixer. The controls in the mixer are: However, I'm having trouble with AC3 passthrough, I'm using ac3dec -C from alsa-tools CVS, and I get no sound. I'm attaching the archive with the output of iecset and /proc/asound/card0/codec97#0/* files during the ac3dec run, and when idle. Maybe the fact that decoded SPDIF output is not working until I pass it through the hw:0,2 has something to do with this, how can I make ac3dec -C use hw:0,2? ====================================================================== Relationships ID Summary ---------------------------------------------------------------------- has duplicate 0001094 nforce4 - optical spdif out not working ====================================================================== ---------------------------------------------------------------------- gilesjuk - 07-20-05 02:12 ---------------------------------------------------------------------- Fixing the output to 48Khz allows me to play mp3s fine. Eg. mplayer -ao alsa:device=hw=0,2 -srate 48000 Of if using KDE setup arts to use OSS emulation layer (ALSA mode in arts doesn't seem to work for me) and fix the rate at 48000. Anything using arts will then work fine. ---------------------------------------------------------------------- rlrevell - 12-31-05 03:23 ---------------------------------------------------------------------- Is this fixed in later ALSA releases?
