Well, get it then. Or is there some problem with that? ALSA should
support the SBLive.

You mean optical -> rca spdif? Don't know, but will look for myself next
week, since my receiver also has more optical than rca digital inputs.

I don't know about the SBlive but the VIA 82xxx sound chips can be set
to duplicate stereo onto digital out and will switch transparently to
and fro ac3 passthrough, thats what I have here. The trick is to set the
IEC958 Playback (that's digital out) to zero, don't know why, is counter
intuitive for me, but works <shrug>.
