Actually, the HDSP's matrix mixer state is not readable and is
cannot be saved by alsactl.

There is no good solution to doing this on the command line other than creating a script that calls
several amixer commands.  The parameters are described here:

There was work under way by someone to do an OSC controlled mixer
daemon for the HDSP, not sure of its status.
