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 :-)
