amixer cset numid=41 0%

Least on my card that will do it.  You'll want to run:
amixer controls
And look for the numid of what you want to mute(or you can control
everything).  Master Volume on my sblive is numid=41  so a simple
amixer cset numid=41 0% mutes it and 83% is where I normally keep it.

Hope this helps.
