I believe my mixer settings were correct.  The fact that I had plugged in
headphones was detected, the volume icon in Gnome had the headphone icon
next to it when I connected my headphones.  There was just no sound.  Apple
hardware can be problematic, I have never had a similar issue with a PC.

Thanks!

Paul
