Yes and yes.

Yes, because for quite some time alsa defaults to using the dmix-plugin. And
since a much shorter time distributions seem to have picked this up.

And yes, because there are soundcards that allow for more then one app to open
the device at a time. SBLive for example allows 32 (or was it 64) opens and
the meastro3 chip allows 2 or 3 apps simultaneously.

Not to talk about some distributions thinking about adding a single-
soundserver/-system to circumvent a problem which was solved by alsa long ago
after the single-soundserver solution named aRts/esd didn't work out...

Have fun,

Arnold
