If only it were that simple...
The default "ALSA:default" device on some sound cards (i.e. SoundBlaster
Live! and any other "hardware" sound cards) allows multiple applications
to output to the sound card simultaneously on ALL versions of ALSA.
The default "ALSA:default" device on all sound cards (even "software"
sound cards like the NVIDIA NForce2 and other intel8x0-based cards)
allows multiple applications to output to the sound card simultaneously
on ALSA 1.0.9 and above.
If the user re-defines the "ALSA:default" device in his/her ALSA
configuration, whether multiple applications are allowed to output to
the sound card simultaneously depends on the sound card and the user's
custom definition of "ALSA:default".

Actually, it just requires upgrading your ALSA to 1.0.9+ or configuring
your ALSA properly (which works whether using ALSA 1.0.9+ or not).
(even if you're not using digital sound).
