I just purchased one of these:
Atlona AT-HD570
It retails for $230.
It will take in any type of HDMI signal (including 3D), strip the audio out (either bitstream, LPCM7.1 down to 2.0) and send out the audio signal via analog mini connections or toslink/optical as well as pass-through the HDMI video signal.
This worked nicely for me to run hi-res audio via HDMI to my main display and output video from a switcher through this device to allow for simultaneous 2-channel audio to play through a multi-room system.

That's a nice bit of kit but note the following limitations:
1. You still can't do dual audio where the two audio streams are of different types e.g. one 5.1 and one (mixed down) 2.0 - the 2.0 feed is going to be missing all surround info. Best you could do here is to use a dolbe encoder to mix the surround channels back in to a 2.0 stream.
2. Only uncompressed audio can be output to the analog connections, so DTS-MA will only be passed through HDMI. AFAIK, XBMC cannot decode DTS-MA so you can at most get DTC core output to analogue. This is a restriction of HDMI licensing or somesuch legal nonsense rather than a technical limitation.
