Help re-enable auto-switching to detected incoming audio
I purchased a TX-NR727 a few months ago to replace a HT-RC370 that broke. No other components changed.
I have an 4x2 HDMI matrix that I use for controlling inputs/outputs, so the TX-NR727 really only needs to stay on a single input/output at all times.
My old HT-RC370 was set up in such a way that I did not need to switch video/audio inputs between the HDMI input and my Sonos analog outputs. The receiver defaulted to the HDMI audio, but if there was no HDMI audio being received, and I turned on the Sonos, the receiver would automatically switch to the Sonos analog audio. I believe the Sonos analog RCAs were actually on the same input as the HDMI input.
This was very handy for my wife, and because you can turn on the Sonos in any room, but switching inputs begins to complicate things.
I've searched everywhere and I've tried every setting in the OSD and in oRemote and cannot find a way to make auto audio source switching work. (I use oRemote on my iPhone almost exclusively to control the receiver)
I have a feeling that I could hack ARC (I have no use for ARC currently) to do get the receiver to auto-switch (this receiver would do that, correct?) for me if I picked up some strange hardware to convert the digital or analog Sonos outputs and piggyback the signal on the HDMI matrix output.
I have few follow ups to also optimize the music/settings problems I'm having:
1) I don't have great hearing so I usually have the center channel at 10 for tv/movies. But this is clearly not optimal for music. I do enjoy some of the Audyssey music settings over stereo, but it's annoying to turn down the center channel (and turn up the sub). Unfortunately, the simple center/sub/bass/treble settings seem to persist across receiver video inputs as well as between single video inputs and the audio inputs. Is there a better way for me to do this?
2) Instead of using the analog Sonos outputs, is there a way for me to leverage the digital optical or coaxial Sonos outputs for auto switching?
3) I don't like leaving the subwoofer (Polk Audio DSW PRO 500) on, and in stand-by it seems to annoyingly turn off/on a lot at low volume. I never use the sub when watching TV, and I only use it for movies occasionally. But I do like it for music. How can I configure the receiver to not tease the subwoofer out of standby for the HDMI audio input source, but ensure it is on when the Sonos input is enabled?
Thank you for any advice or help, it's greatly appreciated!
