[WINDOWS][PATCH]Bitstream output of HD audio formats

This would indicate a problem with LPCM then. All of the Pirates of the Caribbean movies have LPCM audio tracks on the Blu-Ray release...mine all do anyway, and my receiver indicates MULTI CHANNEL when playing them meaning that it detected LPCM. Kill Bill, 300, Hidalgo, and 3:10 to Yuma have LPCM tracks as well if you have any of those to try and see if they exhibit the same behavior.

If your receiver supports DTS-MA and LPCM, make sure under Settings>>System>>Audio output, that you have:

• receiver supports: DTS-HD Master Audio
• receiver gets other DTS formats: decoded(LPCM)

a stereo downmix (to 16-bits stereo PCM I assume, if you use HDMI).

lol..yea...I've tried about 50 movies and all play HD audio...3 I've found so far not playing ball are Pirates of the Caribbean 1-3 for some reason...

I'm finding the odd one only playing DTS instead of MA so dear knows...

Not the end of the world though....

Hi,

I'm using RC2 version with the HD patch with my system:

- PC: Core2 Quad Q9450 / 8GB / Windows 7 x64
- Graphics card: Sapphire AMD Radeon HD 6450
- HDMI cable to a Yamaha YST-S401 (http://europe.yamaha.com/en/products/aud...t-s401_w/)
- HDMI from the Yamaha to the Philips 42PFL8404H (http://www.p4c.philips.com/cgi-bin/dcbin..._Software)

I have a clean Windows 7 setup (no codecs pack, only DirectX and ATI Catalyst 12.3 with the AMD HDMI Audio Driver). I watch movies using XBMC in the TV (secondary monitor) or using MPC-HC (if I use the primary monitor). As I'm not an advanced user I don't have excesive problems mainly because I don't have a lot of media with HD audio. A big percentage of them are AC3 or DTS.

The only thing I've noted when watching MKV at 720p (I'll post the info for the files if necessary) is that every some minutes, the movie seems to be slow for a couple of seconds. After that it continues well. Any idea about what must I do look for? Is something related to the FPS or Hz? Do I need to configure Catalyst, XBMC or TV with some non default settings? If yes, can you refer to me a guide about that?

For the audio configuration I've set up the following:
- HDMI 7.1
- DD AC3 capable receiver
- Support DTS-HD Master Audio (is this the best sound my receiver accepts, isn'it?)
- Other DTS as decoded (LPCM) (I suppose it doesn't matter because of the other setting)
- DD+ capable receiver
- Dolby TrueHD capable receiver
- Audio WASAPI AMD HDMI Output

Is this config correct?

Any tips about how to configure correctly XBMC for a TV will be very appreciated.

Thanks.

Ah ok...Kill Bill Part 1 plays stereo, 300 Dolby True HD, Hidalgo I don't have and yes, 3:10 to Yuma plays stereo...

My settings are right and my amp does support LPCM! (Pioneer SC-LX85)

Anyone else having this issue? (or am I dimly missing something!)

I have noticed a problem with one specific title on my machine that has been running the last few of these builds (never can reproduce the problem on my other boxes running the regular non HD Audio version).

It occurs in the 2011 title Drive between the 55:00 and 55:10 time sequence, one car starts to overtake the other and the whole front corner of the car in the foreground of the shot pixelates very noticeably. It might have nothing to do with HD audio build (could be an odd-ball video card driver thing or something else) but I have not reproduced it with other machines that are running regular builds.

I thought it was just that my copy of the movie had a problem when I ripped it, so I actually borrowed a copy from a friend, ripped it again and the problem occurs in exactly the same spot, so I suspect it's a problem unique to this title and the HD audio builds or perhaps video drivers for my ATI 6450 causing the issue.

I can create and upload a sample if that would help. I am very curious of anyone else can confirm whether or not they get the problem with the same title that is a straight BD rip.

Check that your windows sound settings are set to 5.1 (or whatever config you have) Its the only way I could effectively playback lpcm and flac tracks as they cannot be bitstreamed AFAIK, but require decoding before being passed to the receiver as LPCM. No doubt DanielaE or DDDamien will confirm/correct this info in due course.

Great work you two by the way

If you want to know what audio is included in your blu-ray disc movie, you can verify it on this site- Blu-ray Disc Statistics

or

MediaInfo

Ah dim it is then

I recently reloaded Windows on my main HTPC and forgot to do that!!! Many thanks!

RC2 is obsolete btw. The most recent build is post-Eden.

Yes, and yes

As before: make snippets of these media files available to me (after checking that those snippets exhibit the same faulty behaviour on your system as the full files) and I am going to look into that. I need to reproduce issues on my development system under control of the debugger to get a better understanding of what's going on. It's as easy as that.

I made a few sample but, unfortunately, I can't reproduce the problem.

I believe the problem occurs when the DVD switches from the menu (with DTS audio) to the main movie (DTS-ES audio). If I go straight to the main movie, it plays fine.
Oh well, don't lose any sleep over it. As I said, it happens only with this particular DVD and I have the movie on Bluray anyway

And a final note: DolbyDigital EX shows as plain DolbyDigital in OSD and AVR. Is this normal?
