Hi,
I have already tried the forum search and google, but without success.
My HTPC does not playback DTS-HD coded movies. Playback stops right at the beginning with the error message "playback could not be started on the selected audio output".
Bitstream is activated. Without bitstream the file(s) plays without problems. No problems with other soundformats.
What i have done so far: copying dtsdecoderdll.dll to the SysWOW64 directory (win 7 64 bit) and all other possible directories :)
i found a topic that mentioned msvcp70.dll and msvcr70.dll, so I copied them, too.
All drivers and MC 17 are up to date. My hardware: Intel i7 3770S with HD4000 via HDMI to Denon AVR 3312.
Any help would be highly appreciated :)
Best
Tom

The file needs to be in \Windows\System32 but when you bitstream you don't need dtsdecoderdll.dll. The DLL is only required if you want MC to decode HD streams.
Why wouldn't you let MC handle the decoding instead (ie, don't use bitstreaming?).
Unless you have a specific reason for that I think bitstreaming only limits your options with MC.

As far as i know i need the HDMI connection for DTS HD, all other Inputs do not support it. And I think it is the best way to let the receiver decode the DTS HD sound.
Is it helpfull to post a log, a benchmark or whatever?

I'm not sure why you can not bitstream DTS-MA but fyi - there are really two "lossless" choices;
1) Bitstream to the AVR over HDMI where it is decoded to LPCM then Amplified: The upside is you get the little lights on the AVR light up saying DTS-MA. The downside is that as the Video is being decoded on the PC and the Audio on the AVR you can get sync issues between the two where the Video Jumps a little on a regular basis to re-sync
2) Decode to LPCM on the PC then transmit over HDMI to the AVR where it is then Amplified: The downside is your little lights on the AVR don't light up saying DTS-MA etc. You also need the dtsdecoderdll to get full bitrate and depth. The Upside is you can use "Video Clock" to keep the audio insyc with the video so no frames are dropped or repeared + all the DSP features.
Keep in mind the "decoding" stage will produce the same LPCM stream regardless of where it is done. It is like "unzipping" a file.

puuhh, after a hard night i solved the problem :)
I could not even get your solution 2) so I was desperate enough to even install XMBC...
To make a long story short the trick was to deinstall the standard Realtek HD Audio driver.
sidenote: I´m deeply impressed about the performance of the Ivy Bridge integrated HD4000 graphic 8)
