Headset problem

[Sixpack]

I have a Compaq SR1910NX with onboard audio. When I plug a headset in the right side will not work. I have checked all audio settings and they are all fine. I've tried other headsets that I know are good and still nothing. I should mention that my speakers work fine, left and right. Any suggestions?

Do the speakers work right plugging them into the SAME jack?

Yes they do. That's what's really got me confused.
