Thanks everybody.

I've finally settled on a pretty simple config, updating the defaults
to use my digital output and use the dmix plugin.


defaults.ctl.card 0
defaults.pcm.card 0
defaults.pcm.device 1

pcm.!default {
        type plug
        slave.pcm "dmix"

I've got myth directly using the iec958 output, and hence locking any
other apps out when it's playing.  It seems the best option as I'm
trying to get straight digital out for all content and dmixing stereo
music with dts movies makes for an unhappy av receiver.

Still a few problems, a second or two before sound plays and my av
receiver freaks out sometimes if you try to play music during a movie
and needs to be turned off/on before it will interpret anything other
than DD/DTS.  (Note to others: keep this in mind when trying to figure
out your config... mysterious breakages can be misleading!)

Good enough though.

Thanks for you help.
