Right. I've got a PC with a 5.1 soundcard, I've connected it via the fibre optic out to the in on my surround amp. Have selected the right channel on the amp, however I get no sound. The soundcard is a Avance AC '97 (I think). It has been set to use the S-Bracket which is installed. But still no sound. Help, I wanna use this as a HCPC but without sound it's useless.
