Yes, I neglected to mention dmix (I do know about it, since I'm in the
middle of writing a Python generator for .asoundrcs, and there are a
fair number of shortcomings in the implementation regarding mmap and shm
implementation :-).

Specific to his example, if he didn't wish to change the sink using
`gstreamer-properties' (or Desktop>Preferences>Multimedia Systems
Selectors in Hoary), changing XMMS to use esd is the most straight-
forward choice.

Yes, dmix is the preferred mechanism, but the preferred mechanism isn't
always the "best" solution. (Consider for a moment why esd was enabled
by default in Ubuntu, for instance.)

This is a helpful hint for him, but the preferred [correct] place to set
such variables is in /etc/sysctl.conf:

dev/rtc/max-user-freq=1024

Then `sudo sysctl -p'.
