I m looking for dual audio output for D-Box HTPC users. Let me try to explain:
a D-Box system is a system which is simply said a moving seating during movies (
http://www.d-box.com). The seating get s it signal from a D-Box decoder (D-Box MCI-2P). This (pc-based) D-Box decoder needs to receive the ORIGINAL core dts/dd signal via optical spdif input in order to work. One can use a simple SPDIF audio card (like the Creative X-Fi surround 5.1 usb). You can connect the spdif output of the audio card to the spdif input of the d-box decoder and from the d-box decoder spdif output you connect the decoder to your avr. Simple as that eh? Of course this way you cannot enjoy dts-ma/true-hd audio.
Over the past years D-Box users have looked for a HTPC solution to be able to use d-box and high-res audio at the same time. Some cable extractors where tried but it never worked (it did not work because the condition of the D-Box decoder is that it needs to receive the UNALTERED core dd/dts signal and with such extraction cables the HDMI dts-ma/truehd signal was converted to dts/dd and so it was an altered signal which makes the d-box decoder not recognize the signal).
So in all these years d-box users who wanted to have d-box and high res. audio simultanuously needed to use non pc player like the Dune or Oppo players which support audio over HDMI and optical toslink at the same time.
d-box always said they where working a a HDMI decoder but it never came......
A few month ago there was a breakthrough and a d-box user on the AVS forum managed to get it working on a HTPC. He created his own (altered) version of Media Player Classic Home Cinema and LAV filters
http://htpcfordbox.over-blog.com/article...40282.html). With his software d-box users can now enjoy d-box and high res. audio with a htpc. All you need is a videocard that supports DTS-MA/TurHD via HDMI out (all cards does this these days) and a second installed audio card (like the Creative X-Fi surround 5.1 usb) with optical output However, the author does not update his MPC-HC/LAV versions anymore and there has been quite a few new versions of MPC-HC and LAV filters with important fixes.
In short
:
What I m looking for is dual audio output simultanously:
- output1 HDMI (NVIDIA GTX460 or just another random card but I use that one) with DTS-MA/True-HD audio
- output2 with DTS/DD core via optical out of second audio card (like my Creative X-Fi surround 5.1)
Can MC17 do this?
Thanks for all input and sorry for my bad English!!
