Something that does this nicely already exists; google for

audioctl.c solaris

You may have to grab it out of the google cache and undo the html-ification;
that's what I did, since the site was non-responsive.  It looks like a fork or
clone of something older by someone else, but of the same name (although the
usage is different).  Seems to work ok for me:

./audioctl -v =75 =headphone +speaker
gain        75   29%
balance     32   50%   m+0   m+0%
ports       headphone 
unmuted

Adjusted:
gain        75   29%
balance     32   50%   m+0   m+0%
ports       speaker headphone 
unmuted

One might want to re-implement this with a more civilized command line.  But
it does appear to do the job.
