Well, with MPlayer cvs I think it at least doesn't do the resampling
"behind the user's back" anymore...
Also from our perspective I really think enabling dmix by default made
the "wailing and gnashing of teeth" a lot louder.
Not to mention it made it much harder to just say "get a non-broken
soundcard" *g*

Hmmm... I know somebody had problems with it. Oded, was that you??

If this is non-optional, better put on a bullet proof vest real fast :-P
(and equip your users with flame-safe clothing if they come here with
their problems *g*).
But seriously, having these two behave differently has often been
helpful in locating the bug (e.g. if it's the soundcard driver or dmix
or...).
