I'm connecting my on-board sound card through a coaxial cable to my receiver 
and then pass analog audio signal from my receiver to the TV. When playing 
music (or TV through MythTV) I get the sound fine through the TV speakers but I 
get no sound through the speakers connected directly to the receiver! The 
receiver incidates that it gets a PCM stream (which passes on as analog audio 
to the TV). When I pass an AC3 stream through the sound card, I do get sound 
from the receiver speakers as expected. I'm pretty sure that music and TV was 
playing fine through the speakers as well at some point (i don't use those all 
the time) and I suspect that it stopped after one of the (kernel) upgrades. One 
more interesting fact is that when playing with alsamixer, I get sound from the 
speakers as well occasionaly when I unmute IEC958 but only for a second or so.

Any idea as to what could be wrong?

Thank you very much

PS: I'm running FC4 with kernel 2.6.16-1.2069_FC4 and aplay lists my card as:

 1 [ICH5           ]: ICH4 - Intel ICH5
                      Intel ICH5 with ALC850 at 0xf7fff800, irq 19
