I can't find the thread now, but it's in my archive somewhere. I was under 
the impression that the native ALSA support in Myth wasn't at 100%; you can 
use output via the ALSA:default doohickey just fine (using it myself), but 
AFAICR you can't specify a mixer device other than /dev/dsp or 
/dev/sound/dsp via ALSA-OSS emulation. I think I remember a post from Isaac 
saying the support was "broken", so a feature request is prolly the wrong 
idea... more like bugfixes and/or additions to the docs.

Again, IIRC, if you use SPDIF passthrough with ALSA:spdif you don't need 
the mixer setting anyway, since the volume would be handled by whatever 
device you pass the SPDIF to. But a bit of a bugger for people like me 
who'd like to excise OSS completely (but what the hell, I'm still using 
2.4), but no major hassle.
