I'm using an a8n-sli board in my HTPC rig I just built. I wanted to use the built in optical out to connect to my receiver but no sounds come out. I updated the realtek driver and still didn't work. I tried using the coax output and that worked for about 3 seconds, now nothing. I did enabled digital and analog output for spdif on the realtek control panel. Anybody else have this problem?
