I've been using a 5 to 1 HDMI switching device from monoprice that works great. Tivo remote "input" button toggles through the devices like a charm. HDTivo, DVD, HD Camcorder and an Xbox360.
I just bought an audio setup that includes a Klipsch Synergy Series Quintet III Microsystem, the the Synergy Series Sub-10 and a Sony STR-DG800 receiver.
I've searched though old threads before I ask for help but haven't seen anyone with my configuration/issues.
I knew going in that this Sony receiver used "HDMI passthrough switching" and was hoping I could make this work. It has two HDMI in and one HDMI out. I thought I would be able to put my 4 HDMI components into the monoprice switcher then go out of that and into the STR-DG800 and out of that and into my TV. Then the only switching I need to do would be on the monoprice switcher using the input button on the Tivo just like I had been doing.
It does indeed switch the video but does not switch the audio. I ran an optical cable and that solves the problem but then everytime I switch to another device I'll have to also change the receiver.
My setup seems fairly common. There must be someone out there that has come up with a clever solution? Or any other brilliant minds out there care to chime in?
