Some soundcards support hardware mixing, some don't. If the card doesn't
then subsequent requests to open the audio device will be denied. The
file provided activates the dmix ALSA plugin which does software mixing
instead. dmix will always allow multiple apps to open the audio device
since it does the mixing itself.
It's not there by default since software mixing does use some CPU power,
and not all cards need it.
