Soundcard: Asus Xonar DSX
AV receiver: Pioneer VSX-324-K-P

I've connected the two together via. an optical cable.

On the AV receiver, I've followed the instructions on pages 15 and 20 of the manual above to switch to optical input.

In Windows, I've right-clicked on "S/PDIF Pass-through Device" in Sound and chosen "Set as Default Device".

In the "Xonar DSX Audio Center" program, I've used the following:



Audio Channel: 6 Channels
Sample Rate: PCM 96 KHz
Analog Out: 5.1 Speakers
SPDIF: PCM (though I've also tried DTS Interactive)

Using the settings above, if I click on the front left or front right speakers, they both come out of the correct speakers that are connected to the AV receiver.

However, if I click on the rear, center or sub speakers, I hear nothing.

Any ideas?

Do you know if your receiver is actually receiving a 5.1 signal from the source? Does it have the ability to display what signal it's receiving? On my Onkyo receiver. It'll display the type of signal it receiving from the source. Right now it's receiving a pcm, 48khz, 2 channel signal from my roku3

Might be optical limitation?

Try regular cables now.
