I've a on-board audiocard with both coax and optical out. I've never got it to work very well.

The card plays perfectly well using analog out, except from the audio quality...

The audio works fine for about 5-10 minutes when using digital out. After 5-10 minutes the sound disapears for some seconds and comes back again. This behavior continues until the computer is rebooted. I started to think that this was driver related. I have a spare Windows disk for this computer as well and I decided to try if it worked better in Windows. I have the same problem in Windows so that eliminates the driver theory. Could this really be hardware related? It doesn't matter if I use coax or optical in either operating system. I think that it is a bit odd to think that it should be hardware related since it always works for about 5-10 minutes an then won't work again until rebooted. The reboot part somewhat directs me to hardware but why 5-10 minutes. It would last for seconds if it were some kind of buffer problem.

My guess would be bad cable (does this happen with optical out only or are you saying you have both coaxial digital audio and optical out?) or your receiver just doesn't like the signal that the card is outputting.

I have both optical and coax connected to different input sources on the amp. I tend to not think that it is the amp since it works for 5-10 minutes after a reboot of the computer. I also don't think the cables are to be blamed since I have tried both optical and coax with the same result, it works for some minutes...

I'll agree that it's not the cable if you've used both optical and coax digital connections, but I still would place my bets on the card/receiver interaction. Do you have access to another card and/or receiver for testing?
