I have an HTPC hooked up via HDMI (audio+video) to Onkyo 604 to Sammy DLP. Working 100% for a number of years, loving it, DTS and all.
Wife was bitten by a karaoke bug so I installed some karaoke software on HTPC and it works great, cept mike in.
So my idea is to instead use my Behringer 802 preamp/mixer to mix both the mike(s) and the output of the HTPC into a combined analog L+R and feed that to Onkyo.
All I need now is to figure out a way to toggle my Onkyo between 2 modes:
1) HDMI carries both audio and video - such as when playing MKVs etc
2) HDMI carries only video, the audio should be taken via analog in
Is there a way to go about that ? Ideally just an IR command or a few.
On a related note, I'd also need to toggle the HTPC as well, so that when in "karaoke" mode, it sends the audio out via analog out - as opposed to using the the HDMI audio out.
