HDMI sound output problem from HTPC
I've spent considerable time searching forums and trying solutions, but still cannot get the sound via HDMI working. I'd be very grateful if someone could point me in the right direction.
Custom build based on Asus M4A89GTD PRO/USB3. Until recently sound was sent to 5.1 receiver via optical with no problem. That receiver just broke and was replaced by a Pioneer VSX-S510-s. At the same time, I reinstalled the OS (windows 7 ultimate). With the new receiver, I need to connect HTPC audio via HDMI.
No sound reaches the receiver. Audio however works fine.
The BIOS is set for S/PDIF to HDMI. In the Windows sound settings, I see the HDMI sound output and it's set to default. When playing a video or music, I can see the windows sound volume meter for HDMI moving up and down, as if Windows at least believes that HDMI sound is being played. From everything that I can see in Windows, it looks like all is correct and that it should be working. But, alas, no sound comes out of the receiver.
Naturally, I've tried changing cable. Even buying a high quality 1.4 cable. No luck.
The receiver works. Other devices, such as digital TV box, are connected and they work just fine. Latest AMD drivers have been installed and reinstalled. All imaginable HDMI settings in the control panel have been changed back and forth to try to get results. Nothing worked so far. Windows is happily pretending to be playing sound while the receiver refuses to acknowledge any.
In my desperation, my next step will probably be to buy a discrete graphics card to see if the onboard one is the problem. Another fresh reinstall perhaps, but since I just did that it seems unlikely.
And why not just use optical as I did before? The Pioneer seems utterly unable to show video from an HDMI source and audio from optical at the same time. Odd design feature. Still, it only has one optical in and I have another optical only source, so it's moot anyhow.
Sorry for the lengthy post. Any ideas would be greatly appreciated. I'm really stuck on this one...
