PROBLEM :

I have a creative inspire m2600 2.1 speaker system with desktop computer. Though the sub-woofer quality declined after an year after I bought it, the speakers are cool. Its volume control unit wasn’t working for 1-2 years. But I was adjusting by tightening the volume control knob. Whenever someone touch the knob, I need to go through the herculean task or re-adjusting.

 

Six months back, I went to a local electronic shop to repair the volume control unit. They said me that the resistor inside the chip went wrong and I need to get the chip or the unit to be replaced. You can see the chip here

I know that would cost me so much for something that I’m not using frequently. So I left it as it is.

Today when I need to watch a movie, I found that knob is not at all working. So I just googled to know whether I can buy the chip from Creative or from Ebay. A lot of other people also had the same problem. Carefully reading through the forums, I got the solution.

SOLUTION : LUBRICATION

Some people solved their knob problem with a little lubricating oil or WD-40 or petrol (I don’t recommend petrol, cause their may be heat and petrol can ignite the knob… LOL)Since I can’t get any petrol or other similar lubricants, I used a lubricant made by mixing coconut oil and kerosene which was there in my store room and it worked like a charm.

Apply 2-3 drops of your lubricant on the knob after disconnecting it (as in figure) from the wires. Keep it open for 2 –3 minutes and then wipe off any lubricant spread over other parts of the chip. Connect the pins to the connector and check your sound system.
