[mythtv-users] one frontend to multiple TVs, changing audio

I'm open to any suggestions on how to do this - I looked in archives and
elsewhere, but did not find anything that seemed like a suitable solution.
What I have is something like this:
mythfrontend -> audio receiver -> hdmi splitter -> 3 different TV sets
What I want to do is that if I am using TV set 1, have full digital audio
output, 5.1 speaker setup, etc, as I will always be using the audio receiver.
If I am going to the other 2 TV sets, I will not be using the audio receiver, so
simple stereo sound is what I need (they only have 2 speakers, and do not
support the full set of audio formats that the receiver does)
I can get what I want by going into the audio setup each time I'm using a
different device, but that doesn't work very well.
I tried using a separate output for digital (mythfrontend does have a SPDIF
port to use in addition to HDMI). However, I don't see a way in mythfrontend to
note different speaker layout, and even with that, the problem is that if there
is digital audio, it does not output any audio over hdmi (I need an option which
says always send data over hdmi, even if digital).
I was thinking that I could have multiple frontends running on the PC, going
out different HDMI/DVI outputs (the receiver has spare ports), but that seems
like overkill and creates a new set of headaches of mapping the correct remote
to the correct frontend, since I'm just using mceusb remotes. It also seems
that frontend properties are per machine, so having 2 frontends on the same
machine would likely clobber each other settings.
I'm think that using the system event to launch external programs could work
to update the database the says what the audio settings are (I already have some
events set up to switch the resolution, since one of the TV's does not support
1080p). But I'm not sure if it is documented where these settings are, and
whether there is a way to get mythfronted to re-read these audio settings
without restarting the process.
Any suggestions/solutions to this?
