After making this post it was pointed out to me there were some terminal one-liners that could acomplish that after you have the alsa-utils installed.  For the sake of completeness and ease of use I am including them here.

To mute the speakers:

Code:

amixer -c 0 sset Speakers,0 muted

To unute them:

Code:

amixer -c 0 sset Speakers,0 unmuted

Also, I have been informed how to put images in my posts. so I will include some screen shots of the first method I used:
