So heres the deal... I just got a blu-ray drive for my HTPC, but I can't get ANY HD audio to out to my receiver. Here is what I'm using for hardware.
MOBO: Asrock Z77 Extreme 4
GPU: EVGA GTX 660 SuperClocked
CPU: Intel Core i5 3330
BD: Pioneer BDC-207BDK
OS: Windows 8 Pro
Software: Total Media Theatre 5 (installed as trial) & MakeMKV
Audio Receiver: Onkyo HT-R280 (from Walmart)
Here is what i've tried.
HDMI from GPU to Receiver with nvidia HD audio drivers
HDMI from MOBO to Receiver with Realtek drivers
HD audio enabled in BIOS
HD audio disabled ind BIOS
Tried switching HDMI cables out
Tried changing HDMI ports on my receiver
Tired uninstalling and reinstalling all drivers
HD-Audio plays fine from same HMDI port using my PS3
No matter what I do, I can't get ANY of the HD audio formats to show up as available in the sound settings. All it gives me is DTS, Dolby Digital and Dolby Digital Plus. When I play a blu-ray using TMT 5 (checked settings, and choose the HD audio stream) it outputs DTS-HD Master Audio as just regular DTS and Dolby-HD as PCM (weird.. right?)
I'm attaching screen shots of what my audio properties look like. I hope some can help me figure this out... it's driving me crazy!
