Audio jack problems

[qmainracing]

I have a T30 that with headphones plugged in, the audio sounds bad. If physically push down on the headphone plug that goes into the headphone jack, the audio gets much better. Is there any fix for this, other than replacing the mb?
Thanks

Try another set of headphones first, it may be the plug.

it is the jack, other head phones sound the same... I fixed it...I went out and bought a $30 USB to audio adapter...I don't want to have to take it apart
