HD Audio

Yes, that because TruedHD is already decoded by XBMC to PCM. If it bitstreaming un-molested TrueHD, you will see TrueHD on your AVR display.

This is why I always tell people to clearly make a list of what they want to achieve before they buy it.

patseguin Wrote:I should hook up that machine I was using for a server which has a a nVidia 430 in it, I bet that supports HD audio. not sure it's worth the hassle though although scrolling through box art on the Zotac is a bit slow too.

If you really want to achieve bitstreaming, GT430 will allow you to achieve it.

patseguin Wrote:On a side note, do you have any idea why my rear spears cut off whenever playing any digital surround sound? I have them wireless for a couple reasons. I did the auto setup on my VSX 53 and everything sounds good. I am wondering if the speakers are getting overblown and that is why the wireless receiver is cutting them off. Do you have experience in this?

I helped a family friend installed a wireless surround speakers. It works fine. Did you perform the Audyssey calibration with it? Or maybe, your wireless speakers are set to cut off at certain ranges.

patseguin Wrote:I Googled PCM and saw this:

"If your receiver is showing PCM that means it is not resampling the audio and you are getting it the way it was truly intended, Changing your receiver to DD ProLogic/ProLogic II MOVIE or ProLogic II MUSIC is forcing the hardware to resample it before outputting to your speakers."

If decoded right, PCM=TrueHD. You shouldn't hear any different.

patseguin Wrote:So I guess it's not a bad thing after all hehe. The thing is it's under MCE with MB. Sound quality is pretty stellar under XBMC though. Should I still give that HDAudio build of XBMC a try?

Since the Zotac is not supporting DTS-HD/TrueHD, it doesn't do any good with HDAudio version in your HTPC. If you want more options, you can try the latest Eden_RC2.

Sorry to say, but I highly doubt that your Zotac is supporting DTS-HD/TrueHD!

I have a sapphire 7970 and dont see the hd audio options you have ?

Dts audio and dolby digital is all i have in there?

Whats that hd audio version of xbmc that one of the devs linked to me? Thats the first ive heard any mention of that.

Missed your post bluray. Yeah i did do the auto calibration. I suppose the speakers could be set to cut off. Would that be a receiver setting or maybe something on the wireless receiver?

As I mentioned, it is not going to do him any good with un-supported hardware!

I'm not familiar with your wireless speaker. You might want to refer to the speaker manual or their website for info....

You have a powerful GPU there. Here are some tips-

1. Make sure that your HD7970 driver is up to date, and you download it from here- Graphics Drivers & Software

2. Make sure that you connect your system this way- HTPC-->AVR-->HDTV via two HDMI cables. Does your AVR supports DTS-HD/TrueHD?
3. Select AMD HDMI audio output in W7 control panel

You should see the options afterward...

Well, I installed my tower with FX8150 and 990FX chipset and gtx430 video card. I also installed the realtek drivers. The default udio shows my VSX-53 as my output device and it supports every single HD audio format. When I look at the spec sheet, there are only 3 supported formats listed, none of which are HD. I alos looked at the Realtek driver and the same thing. Do I need to install the codec before I see those formats listed? The instructions listed are vague as all they show are screenshots of windows. I am experimenting with MCE and MB and all my media plays as "PCM" and XBMC plays Dolby Digital. Do I need to get a different video card in order to support HD audio? I'm almost at the pont of giving up and just using what I have. It just seems a shame to spend $1200+ on a HD receiver only t not get HD audio.
