Headphone Jack issue with T4S

Recently I discovered a problem with my T4S Headphone jack.  I only get sound when I insert the jack partway. If fully insertedthe sound is soft and distorted.    Is there anything I can do to remedy this or will it require a repair? 
thank you, 


Hey Takefive!

Does the issue occur when using different sets of headphones?

I recommend using a different 3.5mm to 1/4" headphone jack adapter too, in case the one in use is faulty.

thankyou,  yes I should have mentioned that I tried an alternate headset, same result

My apologies, The headset has a mini jack and i was using an adapter, I changed adapters and had same problem.  I then changed thenheadset and it is good, the mini jack must have been the culprit.  Problem resolved.  Thank you
