Please, no! This sounds really bad to me (pun intended ;-) I own a card
that can do hardware mixing and really don't like the idea of "being
punished" for that. Especially by something like upsampling almost every
sound I play from 44.1 to 48kHz. And yes, I will notice (is it really
99% of the users who won't? where does this number come from?) -- decent
amplifier, cables and loudspeakers do just that: you start noticing.
The reason I'm really worried here is that I recall Colin Walters saying
that dmix will be on for everybody in FC4:
https://www.redhat.com/archives/fedora-devel-list/2005-January/msg00614.html
Question: will there be a SIMPLE way (a script or HOWTO/FAQ would do) to
turn dmix off for those whose soundcard can do hardware mixing so they
can use their hardware the way it was intended to?
If so, *please* include a note how to do it in Release Notes for FC4.
This would make me happy enough to keep quiet even with dmix set on as
default :-)

Dariusz
