I see that there a quite some people with HTPC knowledge in this topic and I have a question that is a little off-topic but also is close to the things that are discussed here:
Let me try to explain:
I own a D-Box system which is simply said a moving seating during movies (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 core UNALTERED dd/dts signal and with all these extension cables something went wrong that just didn t make it work).
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 and Oppo player which support audio over HDMI and SPDIF at the same time.
d-box always said they where working a a HDMI decoder but it never came......
But 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/art...-89040282.html
). With his software d-box users can now enjoy d-box and high res. audio with a htpc. However, there are some downsides:
- First of all, d-box users are limited and can only use MPC-HC and LAV filters. The biggest downside of MPC-HC is that it does not support 3D so a 3D+d-box+high res. audio is not possible.
- Next there is the author who does not update the software anymore while there has been quite a few new versions of MPC-HC and LAV filters with important fixes. I do not have acces to the source codes.
So what I m looking for is:
Dual Audio Output simultanously via HDMI and SPDIF via 2 audio devices at the same time. More specific: DTS-MA/True-HD via HDMI out of videocard and at the same time the core DTS/DD signal via a second audio card (eg. Soundblaster X-Fi surround 5.1) through SPDIF optical out.
