Just rebuild the HTPC (for what seems like the tenth time...), and have an nVidia 9300 based Asus P5N7A-VM motherboard. Everything seems to have went fine, except for some reason or another I'm having trouble setting up the audio.


I'm using the HDMI output to my HK AVR-254, which then dumps the HDMI up to an InFocus X10 projector. Everything recognizes everything else just fine, but when I go into the sound properties to enable Dolby Digital and DTS Audio, it gets a little messy. Dobly Digital goes well enough, but when I try to run the test track of DTS Audio I get the following error..


"Windows was unable to play the test tone. Support for this format will be disabled."


I also get the same message for Microsoft WMA Pro Audio, but since the I'm pretty sure the receiver doesn't support it I'm not too worried. I've got the latest drivers for everything, and Vista X64 up to date, so that should be OK. I've tried flipping the sound configuration from 5.1 to 7.1 in both Vista Media Center and the Vista sound configuration, and it doesn't seem to make a difference.


According to the Factual & Unbiased HTPC HDMI HD Audio + Video Roundup Thread the motherboard SHOULD support both Dolby Digital and DTS, but it doesn't seem to want to flip out of the 5.1/7.1 PCM mode. This is problem is made even bigger by the fact that the media I try to play that should be Dolby enabled (live ATSC HD, recorded ATSC HD, and even a DVD image) comes up with no audio. Any suggestions you guys have would be much appreciated!


Hardware configuration:

Asus P5N7A-VM motherboard

Intel E6850 3ghz C2D CPU

nVidia 8500GT (in Hybrid-SLI mode)

2x2gb Corsair DDR2-800

Hauppauge HVR-1800

Hauppauge HVR-1600

Vista Home Premium X64

Windows doesn't have a built-in DTS filter, I believe. That might be the issue because that happens to me sometimes but once i get all my filters installed correctly, the tests run fine.

Well I do have PowerDVD 9 installed (v9.0.1719.0 specifically), as well as VistaCodecs 32/64bit installed (v5.3.5 and v2.0.3 respectively). I'm pretty sure that PowerDVD would square that away, right?

I'm running the same MOBO, just curious, why are you using an nVidia 8500GT? Why not just use the onboard 9300?

The AC3 filter is already installed, as part of the VistaCodecs pack; it's currently at v1.61B.

I'm using the onboard 9300 in conjunction with the 8500GT. The system utilizes the second GPU in whatever it's doing, so instead of having two low-end GPU you've essentially got one mid-grade GPU.

Well, I figured it out. I think. For kicks I reverted back to the HDMI driver v1.33 and found that it worked. The ATSC TV that I've recorded comes up as "DOLBY PLII MOVIE" on the AVR, and the MKV files I've got kicking around come up as "DTS" on the display. I checked the configuration and it had me as stereo on both VMC and Vista, so I changed it to 5.1 and I was in the same boat as before. I changed Vista back to stereo and left VMC at 5.1 and it worked.


So I updated to 1.42 HDMI drivers and tried the same thing, and it seems to work. I tried to run the DTS test but it failed (as before) so I checked it off anyay, checked all the sample rates up to 96khz. Back into VMC, and the AVR is still pulling up the right sound configurations so I guess that fixed it.


What I'd like to know is why it bugged out when it's configured for 5.1 speakers, but is fine for stereo. I'm pretty sure that DTS isn't some stereo-mix business, so it seems like it wouldn't work, but whatever. I'm happy with the way it is!
