Yeah, my HTPC is just outputting HDMI directly into the Onkyo amp. Both Video and Audio.
The PC sees the Amp fine actually, When I turn it on, I can tell the additional audio device appears, when I select it (sometimes it says Onkyo, sometimes it's blank, not a big deal) I can configure the speakers, and it comes up with a 7.1 option, and can select the speakers size, etc. then confirm its setup correctly.
This is the Win7 SP1 x64 Windows audio configuration, no need to install anything else, as when you do the speaker test, all 7.1 speakers make there little sound (albeit the end of the sound as the amp switches every speaker on/off).
The problem (which wasn't a problem a few nights ago, until I started fiddling with it again! Arghhh) is when you use software like VLC (Doesn't work with HD audio at all does it?), Media Player, MPC, MPC-HC. All of the software I have installed/uninstalled/added filters/removed filters/etc is where the challenge comes in.
I was under the impression that I needed all this "stuff" to get my amp to play true 7.1 on my 7.1 setup through the PC, because it couldn't without it.
What I am really looking for from the Guru's here is a simple way to "Bitstream"? Or just dump the signal as it is without fudging with anything right to my amp which should be more than capable of doing the rest. Correct?
How can I make any of the tools I listed above just dump the audio without touching it? I want to be able to do this for .mkv's (like Abc123.DTS-HD.1080p.mkv), or full Blue Ray's I have ripped to the HD to play. Of course this is no issue with my BluRay player on full BluRay's but I like to have my collection on the HD for easy/fast access.
Hope that is enough info, and I think I am taking the thread off topic a bit if all I really need is Bitstream? Appologies, I will start my search in that direction now that I am perceivably on the correct path forward. Any help would be much appreciated.
