Can Media Center playback DTS Audio DVD's over spdif?  I can play the DVD's using PowerDVD 8, but PowerDVD 8 doesn't pass through the audio to my receiver.  It seems to downsample the stream to 2 channel audio and them my sound card send the PCM to my receiver. 

When I try to play the DTS Audio DVD using Media Center all I get is hissing.  Do I require a special codec to play .cda file types (this is the file extension for the DTS Audio music files) with Media Center?

Any help would be appreciated.

Technically DTS 5.1 audio CDs are standard audio CDs. The DTS stream is encoded inside the standard Red Book audio CD format. You would need to be able to pass bit perfect audio through SPDIF to your external DTS decoder.

I have been able to do that when the following conditions exist:

- The sound card supports 44.1 kHz sample rate natively without resampling.
- The sound card has ASIO support & correctly working ASIO driver.
- MC is set to use the ASIO mode.
- All DSP (digital signal prosessing) is disabled in MC. This includes all settings in DSP Studio, internal volume (set it to the max) and crossfading (set the playback mode to gapless).


For decoding the DTS signal on the PC you can use the AC3Filter DirectShow filter. Probably you would first need to rip the CD in wave format and play the wav files instead of the CD. You can configure MC to play the wav files through DirectShow.

Oops, somehow I read your question as "DTS audio CD".

What exactly do you mean by "DTS audio DVD"? Do you mean a standard video DVD with a DTS audio track or a DVD-Audio disc that has the DD and DTS audio tracks for standard DVD player compatibility?

EDIT

Actually, I think you mean DTS audio CD (aka 5.1 Music Disc) as I assumed, because you mentioned the .cda files. Windows displays audio CD tracks as .cda files. (This is a display only thing. Audio CDs don't contain normal computer files.)

When I said DTS audio I meant a DVD-Audio disc that has DTS audio tracks for a standard DVD player.  I downloaded and tried to use asio4all.  I am no longer hearing the static that I was hearing before.  Now I don't hear anything, but Media Center shows that the file is playing.  I am using Turtle Beach Montego sound card with Microsoft XP.  Any other help that you could offer would be appreciated.

If the format is DVD-A then the disc does not contain .cda files. The standard DVD player compatibility files are in the standard video DVD format. (http://en.wikipedia.org/wiki/DVD-Audio)

Can you post a link to the disc details? (publisher, Amazon, or...)

I assume you have the version II, which has digital outputs. According to the manufacturer's data sheet it has options for the 32, 44.1 and 48 kHz playback modes, so possibly it can pass unaltered audio data through SPDIF. However, the card is very old and it is difficult to find info about its actual capabilities and compatibility.

Here is the link to the album - some people are saying it is not a DVD-Audio disc:

Well after quite a few months of random troubleshooting I got down to serious business trying to figure out why DTS encoded DVD's just didn't seem to play back correctly in Media Center. I'd get audio that seemed to clip and quickly reduce in volume, then slowly come back up again. Source DVD was fine when played back on a DVD player, but in MC - well it was very annoying.

I have a repeatable section of David Gilmour Live in Gdansk at about 6:20 seconds where the volume would get clipped.

After messing with just about every setting I could find I could get no satisfaction. Even WinDVD version 6 had the same problem. I was seriously starting to think it was my Surround amp.

Then I messed with the AC97 Audio - running straight from the SPDIF to the amp. Same problem.  Then I messed with the audio driver a bit more - and found a setting to use 6 speaker 5.1 audio. So I set that and MediaCenter would no longer play a DVD. It directed me to a webpage to buy a DVD driver. While on the webpage I decided to download WinDVD version 9 - and guess what?!?!? The problem is GONE!

Media Center still won't play a DVD unless I pay for the $19.95 driver. WInDVD is $39 and I know it will work.

Which do you think I should buy?

I think the "buy a driver" message was the default Windows Media Player/ Windows message. I don't think JRiver is directing you anywhere.

MC can play DD and DTS audio tracks if your system has correct Direct Show filters installed and correctly configured. In my experience you don't need to buy any commercial product. There are free alternatives.

Have you read the DVD playback article in JRiver's Wiki? http://wiki.jrmediacenter.com/index.php/DVD_Playback

well. it is easy in 12 to get that message, i posted a few times about it:


after clicking ok

how it looks normaly:


it happens for instance when opening the dvd playback settings in options and listening to some music at the same time.

 
gab

its not difficult to get this in 13 also.
