Left speaker problem pls help

[koji]

I have a 2.1 Speaker from Edifier. Sometimes the left speaker is working but most of the time it wont. The speakers are connected to the bass and the bass is connected at the back of the computer.

 

When I try to unplug the jack connecting the speakers and bass and try to put it in just a little. Sometimes I get sound from the left speaker and the right speaker gets no sound. That's all i know.

I've tried twisting the cables while properly plugged in to check if maybe the connection from the wires inside just got cut. But there are no changes with any twist I do so maybe the problem is not wiring..

Please help me. Or give me advice on what could possibly the problem is. Thanks a lot!
