Actually when it comes to the # of speakers, I've found that the best way to do it is simply let my receiver handle the downmixing. I THINK that most modern receivers are able to downmix - say - 7.1 to <whatever is connected>
I had similar problems to yours when I tried to tell XBMC that I had a 4.0 setup, but just pretending I have a center and subwoofer and letting the receiver handle the rest seemed to be a sure-fire way to get things to be downmixed properly.
I had, literally, 5 minutes this morning to play around with this stuff and well Im afraid I didn't get it to work. Need to spend a little more time on this to get back into the tweaking mode.. can someone remind me: how do I check if an asound.conf is found, read properly? My problem this morning (again.. 5 minutes..) was that it simply didn't have a new 'virtual' audio device, so it seemed like it simply hasn't read in asound.conf or there was a parse error.
I seem to recall aplay does give some feedback on the proper-ness of asound.conf...
Anyway, nice progress, more later!

I haven't tested this as an asound.conf as my initial tests in that configuration failed. This is an asoundrc config that should be located in your home directory (~/.asoundrc), that way it will be read every time you try to play a sound and can be edited on the fly. Place the file in the correct location and restart XBMC and you should be good to go.
speaker-test is useful for this.

Interesting. With some minor snags I think I've got it to work.... better than I thought?
One setup I never considered is to _always_ let my audiophile DAC take care of the front speakers, rather than have an "audiophile mode" where I manually switch to the stereo path. (primary reason is the theory that there would be different delays, which likely is true but I'm not really noticing it yet..)
But the first thing that happened when I got everything lined up properly was basically fronts producing, well, front through my DAC, and rears going through my fine-but-nothing-special receiver.
The only snag is that center is way under-amplified. Subwoofer too, I suspect.
I think we're very near switching this topic to 'SOLVED' guys, but the key issue that I had before was stuttering, blips (cracks) in the stream etc. Need to watch a movie or two to see if they manifest.
More experimenting to come.

Thank you guys for all this superb work. Just one question to omobeanz: your using "rate 48000" in the config file. As a result the signal is resampled to 48000 kHz for both HDMI als the DAC isn it?

I'm pretty sure you can remove the 'rate 480000' entries. Give it a try?

I would like to. However, my current DAC has no display and therefore cannot tell me the bitrate XBMC / Openelec is sending. 2 weeks ago I tested the config of hannesb in the local audio store with my potential new DAC. In case of the config of HannesB and using an AMD APU the signal was resampled to 48000 Hz without even defining rate 48000.

confirmed - removing 48000 works

After a little fiddling I've got it working: stereo output to my amplifier and also audio over HDMI to my television, thanks to omobeanz' setup. Very nice work, been looking for this a long time.

On another note, has anyone figured out how XBMC decides on the names for the audio output device in Settings -> System -> Audio ?
I'd love it to actually be more descriptive than "Default". (Dual-Audio sounds good...)

Has anyone got this working for openelec?
I want to do bistream to HDMI and audio to analog. I dont care if it doesnt work with bitsreamed content, I only want it to work with 2 channell stereo.
