Chaintech AV-710 - No sound from digital out
I'm trying to get the optical output to work from a Chaintech AV-710 sound
card. T'm running Fedora Core-5.
Turning the IEC958 Output on/off in alsamixergui turns the optical on/off (i.e. light out of optical cable).
Plugging the optical cable into my sterio received seems to detect a digital signal when in signal-auto mode, but no music or sound sample plays. I have tried multiple players using source MP3 and audio CDs.
Analog out works fine.
I've tried suggestions from several postings but have no positive results to date. Below is some relevant system information.
