PROBLEM: No sound coming out of my Denon Receiver that is hooked to my pc via optical cable connected to the S/PDIF port. If I set the system up to output to speakers connected to the green port I can get sound.
SYSTEM: Athlon 64x2 processor ASUS M4A78L-M motherboard [root@NN nck]# cat /proc/asound/cards 0 [SB ]: HDA-Intel - HDA ATI SB HDA ATI SB at 0xfe8f4000 irq 16 1 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xfeae8000 irq 26 [root@NN nck]# uname -r 2.6.33.3-85.fc13.x86_64 [root@NN nck]# uname -a Linux NN.FRONT 2.6.33.3-85.fc13.x86_64 #1 SMP Thu May 6 18:09:49 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux [root@NN nck]# uname -m x86_64
SOFTWARE: Fedora 13_64, fully updated.
SETUP: Hovering the mouse over the speaker icon in the top bar shows "Output 100%; 0.0db, RS780 Azalia Controller Digital Stereo (HDMI) so I am assuming that is the default sound output. I went into alsamixer and muted everything except the SPDIF bars in both cards.
TEST: I test the system by opening sound preferences, hardware tab, selecting the RS780 Azalia controller and running the Test Speakers app. I do not get any sound. I have my Denon set to Aux, 0db and Aux is set to Optical 1 and that port is connected to my pc. I can see light coming from the end of the cable when the pc is on.
HISTORY: I have been working this problem since 1JUL10. I first installed MythDora 12 and learned a lot about alsa, drivers, mixers and linux sound then started over from scratch with Fedora 13. I quickly got to the same point.

On my system, I have to enable S/PDIF in the BIOS before I can use it. However, on my machine, it seems to be used only for audio output.
