I have a pair of Cambridge Audio Works speakers and a sub-woofer, and it appears the volume control is giving me problems:
A few weeks ago, one of the channels gave out, so I took apart the control (an odd rotary set-up) and cleaned it, but no improvement.
When I re-seated the jack on the TV, the problem seemed to clear up, so I left well enough alone.
Now I notice the channel is dead again, but when I pull out the stereo mini plug one 'click', the channel starts to work.
Which tells me the signal is getting through.
What would be causing this - a faulty cable, maybe?
Here is a pic of the control - impossible to find these days, I’m afraid:

Leading me to ask - can another be used in its place?
