Hello all. I just got an optical cable so I could pump the sound from my computer through my Yamaha. But I seem to be getting no luck. I have googled my problem but no help was found. I have Creative Labs SB0880 PCI Express Sound Blaster X-Fi Titanium Sound Card. I have made sure to connect the optical in the outgoing on the sound card, and spot 3 (CD) for the yamaha. I have gone into my sound properties and set the output to the optical, it's showing that it's doing audio stuff. (sound bar thing is moving) when I switch output to my pc speakers everything is playing fine. The cable is new and I hope it wasn't doa. Also I have the Yamaha set to CD. With everything at maximum there is no sound. Thanks in advance for any help.
