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...
