Something very similar recently happened to my Inspiron 8000. Two years after buying the thing, the connections between the audio jacks and the mobo were loose. I called tech support, was still under warranty, and they offered to fix everything else that was wrong also, which included little stupid things like a chip in the bezel, and a dvd drive that took an extra second to rev up.

My point being, you've only had this for 6 months.. two years later, and the Dell person was practically begging me to come up with more things for her to fix, gave me a free LCD bezel, as well as sent someone to install it for me, all covered under warranty. Have you tried having them replace it for free?

I'm posting this comment from a Sharp Zaurus SL-5600 at LWX. Just thought that was neat.
