I thought of that.

I tried all the jacks available. No joy. But
here's a question for you - or anyone reading this.... The color of
the plug from the speaker is a dark green. Not one of the jacks on the
computer is that color. I don't know why that would make a difference,
but maybe it does. I don't know. The color of the jack I'm plugged
into now is a pale green. The words on it match what the instructions
say. (And no, I don't remember what it is exactly - I'm at work right
now, not at home.)
And yes, I did go through the troubleshooting guide. The end result of
that was the message that I need to contact someone else.
Thanks for all of the ideas!
