Reset sound card in alsa?

[Paul Galbraith <paul@paulgalbraith.net>]

Every once in a while when I boot my machine, my sound card only 
produces noise and I need to reboot again to get it cleared up.  Does 
anyone know of a way to reset (for lack of a better word) my card so 
that I don't need to reboot the machine?  I'm using 2.4.25 kernel with 
sarge alsa packages.

Cheers,

Paul
