headphone jack work

I have a Dell Latittude D610 Intel 2.13 GHz, 1GB RAM and SigmaTel C-Major Audio.
The audio works with the laptop speakers, but the headphone jack does not.
Anyone knows why? and How I can get it to work? -- MW27

I can't get my speakers to work on my Motion LE1600 Tabletpc but the weird thing is that my headphones work great if I plug into the microphone jack but not if I plug into the headphone jack... I'm wondering if the beta DSP driver, Sigmatel C-Major is sorta messed up...
