When I plug in headphones under Ubuntu the main speakers stay on. The last hardware hurdle this time is sound.

I am able to get the wireless network running, which I was never able to do before (actually, I couldn't get any networking to function before) so right there is a huge, encouraging improvement. I have attempted to use various forms of Linux (including Ubuntu) in the past and been very frustrated.
