The best place to put your stuff is in ~/.asoundrc.  There are global
files, but they're wiped out with new releases of the alsa tools.  If
you want all your system's users to have the same settings, put the
.asoundrc file in /etc/skel/ and it will be copied into all new users'
home directory.  for more information on the .asoundrc syntax and all
the plugins, check the ALSA web page, as well as alsa.opensrc.org (a
great resource).  I know that the dmix plugin can be forced to a
specific rate, it might be possible with plug as well.

You might be able to find your S/PDIF control with amixer -
alsamixer's loud-mouthed hard-to-get-along-with-but-very-powerful
little brother.
