Significantly more info than was previsouly availlable:
from the page:
"For ALSA 1.0.9rc2 and higher you don't need to setup dmix. Dmix is
enabled as default for soundcards which don't support hw mixing."
A caveat from the same page:
"Also, you should keep in mind, that software mixing is possible
only, if all signals are at the same sample rate. So, if you want to
play DVD's, which use 48kHz sample rate for audio, with this kind of
plug, everything will be downsampled to 44.1kHz. Unfortunatelly it
does'nt work wery well (there are some syncronization problems with
some players). In this case you have two opportunities, either use a
separate plug (and loose ability to playback mp3 and dvd on the same
time) or tell your DVD player to sample audio down to 44.1khz, for
mplayer -af resample=44100"
