I'm running an HDSP/Multiface on a planet ccrma
Redhat 9.0 system.  I'm having
 this problem when I restart alsasound.  Below is the readout of `/sbin/service
 alsasound restart`  ... Comments/hints?

That's what happens when you update alsa and something has changed in
the naming or order or whatever of the mixer controls. The state
information stored in /etc/asound.state cannot be properly interpreted
when reloaded by alsactl.
To fix go into alsamixer (or the hdsp* utilities), make sure that all
options are as you want them and then do:
  alsactl store
That will store new information in asound.state. Subsequent restarts of
alsa should give no error messages (until another upgrade messes things
up again :-)
