37.3 Audio Duplex Mixing
Duplex mixing will allow multiple sounds to be sent to the audio card
at a time. Copy
/usr/share/doc/libasound2/examples/asound.conf_dmix to
/etc/asound and restart alsa:
Then multiple command line mplayers can all play at the same time. Be sure to configure xmms and beep-media-player to use the ALSA output device.
When running quodlibet there is crackling in the audio, which is not there when the dmix is removed! Running mplayer and beep-media-player are just fine.
Further details on setting up dmix is available from http://alsa.opensrc.org/index.php?page=DmixPlugin.
