No sound from one ear in headphones?

Basically when I plug my headphones into the front audio jack it only comes out of one ear, and there is a distinct ringing noise through that ear as well.
If I try and plug it in in the rear audio jack no sound can be heard at all- in fact the computers do not even recognise them.

Help would be much appreciated!
