xbox and DTS HD?

post #1 of 15
Thread Starter 
can the xbox 360 output DTS HD high resolution audio? Either through HDMI or Toslink? Or does it just downmixes it to DTS core?
post #2 of 15
I think DTS-HD and DTS-MA include a 1500 kb/sec core. So thats what the 360 will send to your receiver.

PS3 can't decode those formats yet either, but it might be able to with a firmware upgrade.

No HDMI audio on the the 360. Toslink doesn't support DTS HD extensions. You will only get the DTS core via Toslink.

So... does that mean that if you have a video file with DTS-HD, and are connected via HDMI cable, that you'll only get Stereo on your receiver? THat's what I seem to be seeing. If I connect an additional Toslink digital audio cable, will it work?

thx

To be clear -- my xbox is recognized as a multi-channel device just fine by my receiver... I see all 5 channels being used. However, I'm backing up some BD discs using handbrake, and the default settings for ipad/appleTV will include DTS-HD AAC and DTS-HD AC3 audio streams. When I play these files, I just get stereo on the xbox. That's what I'm trying to fix.

thx

Actually -- I may have misspoke. It looks like Handbrake is mixing a DTS-HD track down to Dolby Pro Logic II in both AAC and AC3 audio streams. Seems like Dolby Pro Logic II should sure work, doesn't it?

thanks for any help!

it's pretty bad taste to take the name of someone else unless you actually are Joe Belfiore.

It says join date of 2004. Who had heard of Joe B then?

However, If the person really was Joe B he could have just pinged one of the internal MS DL's and got an answer a lot quicker.

It never even occurred to me that signing in and asking a quesiton would generate a question! I just want to get my BD backups playing on my Xbox. smile.gif The 2004 join date is a good point. I was working on media center back in 2004, AVSforum was a natural place to hang out.

Honestly, I think AVSForum is more likely to give me a good answer than me trying to hunt down the right person at MS. Yes of course people at MS will know, but I was betting there's "crowd wisdom" here where somebody could just say "yeah, the latest dashboards never fixed this, so it still doesn't work" or "you need to encode to and you'll be fine" or "just don't try do it over the HDMI cable".

thanks again if anyone has info on this. (But I'm guessing maybe you folks don't since nobody has answered.)

PS - I have the shark codec pack installed on a Media Center PC... and when I tried playing the same video files through that (HDMI connection, same receiver), they also play in stereo. I was going to try the K-Lite codecs to see if that's any different. Not sure if this fact is helpful, but I thought I'd add a little extra info. Happy to run some tool that tells exactly what the audio stream(s) are.
post #14 of 15
I ran MediaInfo on one of the files and it says the audio streams are as shown below. I would expect both Xbox and the PC (Shark codecs) to play the Audio #2 stream in 5.1 ... AC-3 should be fine, yes? Perhaps it's because it's 6-channel AC-3 and neither device knows what to do with the 6 channels? Any ideas?

thanks again for the help!

I don't have the answer but if this was posted in the HTPC forum you may have a better chance of getting the correct answer.

Or ping the 'htpc' DL @ MS and keeping making Windows Phone awesome (err, more awesome)!
