sound only comes out of one speaker?

[IgniVellex]

I have a set of klipsch THX promedia 2.1 speakers and for some reason sound only comes out of the left side

How are the speakers connected? If via 3.5mm aux, make sure it's pressed all the way in.

Turn the plug slowly and see if it changes anything.

Try plugging the speakers into other audio sources, like a smartphone, tablet, or laptop. (Ones that still have 3.5mm audio jacks, of course.) If the speakers still don't work in multiple audio sources, there's likely something wrong with the speakers themselves.

 

Based on the wiring diagram, it appears the speakers receive audio signals from the subwoofer unit via Spring Clip terminals, which means you could also try swapping the left and right speaker connections to narrow down the issue.
