Setting up 5.1 audio via S/PDIF in Windows 7?

Question

Iron

There is a computer with Win 7 on board
There is a 5.1 receiver with support for DTS and DolbyDigital
When connected via a digital output, the sound comes only in stereo mode
At the same time, for movies with DTS or DD tracks, 5.1 works only in Windows Media Player
Movies with regular 5.1 tracks are played back as stereo. When connected via analog, everything is ok.
How to enable 5.1 by default system wide?
- Sound card - built-in Realtek ALC888 / 1200
Receiver Kenwood KRF V4070
latest version of Klite and AC3Filter

Answer 1

I solved the problem by purchasing a sound card with DOLBY DIGITAL LIVE support! (Creative audigy 4) and the actual library of the same name on off. manufacturer's website.
Satisfied, I advise.
Thanks for answers.

Answer 2

I'm sorry, but have you not read this topic

(there are copies on many resources, it was also mentioned on Habré)
?
Perhaps it will help.
You also need to see if the receiver itself is 2.0 or 5.1 on films.

Answer 3

5.1 worked great for me for movies in VLC (in the settings, select "All Options", the Sound section, the "Use S / PDIF if available" checkbox). For the entire system is unlikely to succeed.

Answer 4

“Films with regular 5.1 tracks” - what are these ordinary ones?
Multi-channel tracks for movies can be encoded in different formats (DTS, DolbyDigital, etc.). If the track standard matches the capabilities of your receiver (a bunch of all sorts of icons on the front panel), then it will play multi-channel sound.
If this is a game or something else other than what it can decode, then you will not hear anything.
The sound card in this case can reproduce the whole thing, because its capabilities are not limited to DTS or DolbyDigital.
- Similarity of the solution:
The receivers have modes for virtual decomposition of stereo signals into all 5.1 channels. Usually this is Dolby ProLogic or similar. Check the instructions for your receiver. Then you will have all 5 speakers playing, although the input signal will be stereo.
- And yet, by default, AC3Filter does not seem to have an option for signal output to SPDIF.

Answer 5

Good day! I decided not to create a new topic, the question is almost the same.
there is an LG TV 42" with S/PDIF output on board, a PC with a Sound Blaster X-Fi Xtreme Audio PCI Express sound card on board S/PDIF in, analog 5.1 speakers.
We want to watch DTS movies with 5.1 sound.
with TV everything is OK, the output from the computer is also OK, but there is only stereo firewood in. I
set it up (3-4 years ago) everything worked but the other day I reinstalled Windows and sailed, I remember I also suffered for a long time, help with advice where to dig
