The outputs are not "muted", but the matrix mixer is empty.

You can use amixer with the Mixer control.

Could be done. Maybe at some point I'll add a parameter so that you can 
choose amongst the default hdspmixer presets at module insertion time.

You can do so with a small shell script and the Mixer element of amixer. 
You can find more information on the syntax browsing the alsa-dev 
archive and on the hdsp card page of the alsa-project website.
I plan to add an option to export a shell script restoring the current 
setup in the next hdspmixer release.
