SOLVED
Hello all, I've looked everywhere on the web and I can't seem to figure this out. I don't know if its an AMD driver problem, a windows sound device manager problem, a hardware problem with the GPU, or possibly something else...
I'm trying to hook my Windows 7 64bit PC up to my Denon 1912 via HDMI to get 5.1 or 7.1 for gaming and movies, and pass the video through from the receiver to my TV.
The problem is that my PC is only recognizing my Denon as a 2 channel receiver when it is in fact a 7.1 receiver.
My GPU is an XFX Radeon 7850 1GB, and it is supposed to integrate audio processing and supports all lossless HD audio codecs and lower (DTSHD, DDTrueHD, PLXII, etc etc.). I don't know the specifics of how it's actually processed - whether the GPU itself processes and outputs the audio, or if it delegates it to my soundcard and collects the output from there to pass through with the video - but I DO KNOW that my old 6770 had no problems hooking up to my receiver.
When right clicking on the sound icon in the system tray on my PC and selecting playback devices, the HDMI sound device is only stated to have 2 channels.
I tried plugging in an optical cord so that the realtek would handle the audio, but the problem persisted. This time, my Denon was recognized as being a 5 channel device (which makes sense because I was using an optical with a max handling of 5 channels), but when playing games that I know have full 5.1, I wasn't getting 5 channels, only 2.
Of course I could still get sound from all my speakers with just a few clicks of the remote, but not discrete sound (I tested in games by doing things like standing in front of someone talking or something on fire then turned my back on them to, and the sound didn't come from my rear speakers as it should have with discrete sound.
All speakers are hooked up correctly...everything concerning how I have it wired is definitely correct. My PS3 plays full 7.1 movies and 5.1 games without a hitch.
I've tried 4 or 5 different AMD drivers, starting with 12.11 beta, then rolling back to something like 12.4 and selectively downloading and testing a few in between the two and restarting my PC after every driver install just to be sure...nothing changed.
So I'm wondering if anyone has any ideas about a fix for this? Or if not a fix, would someone know for sure what the source of the problem is (i.e. is it a realtek driver issue, an AMD driver issue, a microsoft update issue, a Denon firmware issue, etc.)?
Another possible problem could be that my PSU isn't adequate maybe? Might be a longshot but the card does draw quite a bit of power and I'm running one 5400rpm HDD and another 7200rpm, as well as the fans and so on, on only a 450W. A decent 450W mind you, but still I thought perhaps the PSU cant deliver enough juice on one rail to process a demanding game AND 5-7 channel audio
BTW I hope this is the best forum for this post...since I can't really isolate the source of the problem I wasn't sure which forum/subforum to post this in.
Let me know if any more info is needed if you think you might have a hunch, and thanks in advance for your input
