Perhaps your card is still configured for analog out only. What does : aplay -Dspdif xxxxxx.wav do ? > First off, is there any good source of documentation on the > /etc/asound.conf file? http://www.alsa-project.org/documentation.php is in general a good way to start. Anyway asound.conf is the system wide implementation of asoundrc. So, the documentation for asoundrc should apply here. I've installed a new soundcard myself yesterday and didn't need to touch any other file than /etc/asound.state to make it work for optical spdif. Actually the card can also do analog and spdif at the same time which not every card can do I believe. It's a terratec Aureon 5.1 PCI card which I can certainly recommend. I had everything working in FC3 in just a few minutes. I also suggest to use gnome-alsamixer to set the mixer settings. It's much easier than alsamixer. After you set the mixer controls correct, you can use "alsactl store" to store them. > Also, can somebody explain the purpose of the files in /etc/alsa and > /etc/alsa/cards? No /etc/alsa or /etc/alsa/cards here. Mine are in /usr/share/alsa, perhaps because I installed some newer packages from different repositories (atrpms.net). I think this just holds some default configurations for soundcards. Regards, Marcel
