99% of the users is a random guess. I'm talking about any user here, not
technical user specifically. The idea is that dmix is only there when
needed. If your card doesn't support mixing, well, you don't expect
anything else, do you? You can't ask for the impossible. If you card
does, then turn it off. It's not that hard. (And yes, this should of
course be auto-detected, we're working on that.)

I'm sure the fedora people will do that, obviously, but I (for the
GStreamer side of the thing) prefer to do the right thing automagically.
I'm not sure that'll be finished by FC4.
