Connecting Audio from PC to Stereo via Optical

Hi

I have an Insignia stereo receiver, and a Vista 64 PC with an evga mobo. My mobo has optical out, and my stereo has optical in.

I bought the cable, hooked t up, and I cannot for the life of me figure out how to make the sound work.

I tried all the presets on the receiver, messed around with the sound in Vista, but I'm lost.

Please, any info would be great.
Thanks

There is no spdif as output.
I figured out the default for the optical is Video 2.
But now it won't let me select the stereo setting I want, which is Matrix.
And it only plays music from WMP, not iTunes.
Why is that?

I figured that out. I can hear the music playing from WMP, but will not play from iTunes. I also cannot select any other music setting on the reciever. I usually use Matrix, but won't let me. Every other setting makes it sound terrible.

Once optical is selected some audio enhancement will be disabled, including matrix. For that you'll need to turn your amp DSP system set to matrix.

You also may have a driver problems if you can't play iTunes without audio, have try reinstalling iTunes?
