Since upgrading my surround sound system and PC I've been reading this forum trying to find an answer to one problem I'm having - getting HD Audio from my PC to my AVR.
This is my current setup:
Gigabyte GA-970A-D3 with AMD FX4 processor & 16GB RAM
Asus Radeon HD5450 1GB graphics card
OCZ Agility 128GB SSD
Onkyo HT-R358 AVR 5.1 system
Samsung UE46C7000 LED TV
Windows 7 Ultimate x64
Connected as follows:
HD5450 --> HDMI --> Onkyo HDMI4, Onkyo HDMI Out --> HDMI --> Samsung TV
All the latest Radeon drivers are installed on the PC, and I'm using the latest version of MPC-HC. I've set up MPC-HC as per the guide on this website, but whenever I play a film that has HD Audio I don't get the full HD. To test, I've ripped two BD movies to my PC as .m2ts files with no conversion/compression (using ClownBD), just the main audio track. Avatar has a DTS-HD MA track, but when I play it in MPC-HC or PowerDVD I only get basic DTS. Cars has a TrueHD track, but I only get PCM 5.1 when I play that. If I play the films from the disks on my Bluray drive in the PC I get the same result.
I've tried the EDID override that was posted, and I've tried installing ffdshow Audio and LAV Audio (not at the same time). I've currently got LAV installed, and it shows that the decoder is being used when I play a film, just not the correct format.
If I play the films through a standalone Samsung BD player they are fine, and the correct audio is heard.
Am I missing something really obvious, as all the guides seem to suggest that this should work with my setup. I did check before I bought the Radeon 5450 and I'm sure it did say it supported HD Audio.
Thanks in advance!
