ALSA configuration files
------------------------

System wide config file (/etc/asound.conf)

# for OSS emulation to use the dmix plugin
# ALSA applications can just use it with device "plug:dmix"
# but we set the ALSA default anyways

# according to http://alsa.opensrc.org/index.php?page=DmixPlugin, dmix should
# be enabled by default starting with ALSA 1.0.9 (at least for soundcards
# without HW mixing support)
# some of the following has been taken from 
# http://www.novell.com/coolsolutions/feature/16675.html
