I've been using SCS for a little less than two years, so forgive me if there's a way to already do this, that I just haven't discovered.
I'd like to add an option check box or pull-down that allows SCS to do audio "pass-thru" direct to the HDMI out of the PC, when playing a video with a multi-channel AC3 or DTS audio.
Background... we occasionally do private "friends and family" movie viewings. I'd like to add a video cue and have the multi-channel soundtrack pass-thru to the HDMI out along with the video and let the video device's built-in AC3/DTS decoder handle it. We have a dedicated AC3/DTS processor. This would mean SCS wouldn't need to process or decode the audio, just pass it along.
This would be on a cue by cue basis.
When the movie ends, we can activate the next cue, to bring up the house lights.

Re: Multi-channel AC3 / DTS Pass-thru
...a little info behind this request.
Our Community Theater uses SCS to send 10 audio channels from a PC to a Mixer, and HDMI through a 7.1 Surround Decoder to a Projector.
Normally, SCS Slides or Video for stage plays just pass through the 7.1 Decoder (unused), to the projector.
For private functions like movie screenings, we have a Media Player, Blu-ray, and Ad player. All these other devices also route through the 7.1 Decoder. The Decoder processes the AC3/DTS soundtrack (sends it to the Mixer) and forwards the video to the projector.
We'd like to be able to use SCS to cue multi-channel video files (mp4, mkv, etc) for playback and PRESERVE the audio channels.
For this there would appear to be two possible solutions:
1) Have SCS decode AC3/DTS and patch it to user selected outputs, or
2) Have SCS pass the AC3/DTS straight through the HDMI out to let an external decoder handle it - in our case, the 7.1 Decoder.
Option 2 SEEMS like it may be easier to implement.
Option 1 would require a drop-down box to choose WHICH audio stream to decode, then a patch interface to make sure that each channel is correctly routed to the necessary audio outputs.
The desire is to automate playback.
1) Bring down house lights,
2) Play a preshow Cartoon or Newsreel,
3) Play a fun policy trailer or two,
4) Play main feature,
5) Bring up house lights during credit roll (using a timer).
That way, once programmed, a volunteer can easily "launch" a private viewing and walk away from the PC.
