S/PDIF Optical out - No sound from receiver (onboard and sound card)
I've got an Asus Crosshair V Formula motherboard that I couldn't get any sound on my Onkyo HT-R550 receiver via the onboard optical output (Win 7 Ultimate 64 bit OS) I was planning on getting a nicer sound card anyway, so I bought the Asus Xonar Essence ST.
Installed that sound card but alas, I still have the same problem.
Speaker and headphone outputs work, but no signal is recognized by the receiver via the S/PDIF. I know that the cable and receiver are fine, I still have my previous computer which is running Win XP and it has been sending audio via the same cable to the same receiver for years. It still works if I hook it up. It has an Asus M2N-SLI Deluxe motherboard and an HT Omega Striker 7.1 audio card. Both the onboard and sound card optical output work with the optical out to the receiver.
With my current computer the Win 7 "Sound" window displays signal on the audio meter when I play audio or when I use the "Test" function. But no signal is recognized by the receiver. I've tried every format and sample rate. I've uninstalled all drivers and reinstalled. I've used DH Driver Cleaner to sweep out all previous existing audio drivers. I've also had the onboard disabled since I originally installed the card. I've tried everything I can think of and manipulated all the settings in the Xonar Essence ST Audio Center software that are relevant. I think I've tried everything, but I'm hoping I'm wrong. I've submitted this to Asus technical, but it's been 5 days with no response, so I figured I post it here.
I've Googled the heck out of this for the last week and haven't found anyone with the same problem, or at least, none of the solutions were effective for me. This really should not be this difficult. It was practically "Plug & Play" with my previous computer. I'm strongly suspecting a Windows 7 issue, but I have no way to verify that currently. For what it's worth I'm using the only driver available that I'm aware of: Xonar driver 7.12.8.1794
Anyone with any suggestions or ideas? I'd greatly appreciate it.
