Dmix is part of standard ALSA and is thus available on any recent Linux system. You are of course right that dmix is not commonly configured to be part of default plugins. But most ALSA apps allow you to specify which soundcard to use (the usual implicit choice is 'default'). If you specify "plug:dmix", you'll get dmix output in most cases (unless user has overridden the asoundrc configuration). For example: aplay -Dplug:dmix foo.wav alsaplayer -o alsa -d plug:dmix ecasound -i foo.wav -o alsa,plug:dmix This works on my system with vanilla alsa-lib-1.0.4 (quite old version in fact) without absolutely no modifications to any ALSA configuration files (I don't even have a ~/.asoundrc on this machine). So I assume this should work out-of-the-box on any system that has recent ALSA (SuSE systems, FC2 and newer, Mandrake 10 and so on).

Together with JACK they form a killer combo. :) I use JACK when making music (ability to route audio between apps, transport control), and dmix when listening to mp3s (wide application support, no need to run nor configure any servers; still great performance ... also latency-wise!). -- http://www.eca.cx Audio software for Linux!
