Altec Lansing FX6021 Subwoofer Problem

I have an Altec Lansing FX6021 2.1 system on my Dell with Vista Home Premium. The bass on these speakers goes out and comes back for a week, then goes out again.

I originally thought it was the sound card, but after trying out my Ipod on the speakers, the same thing happened. I then knew it must be the speaekers.

I unplugged the controller cord (cord from sub to volume dial) and plugged it in again, and heard a loud POP in the speakers. They then started working again.

Now a few weeks later it has happened again, and this time when I try to re-plugg the controller cord, nothing happens. I cannot get any bass response from my sub. The speakers work still, but the sound is very tinny. Why is this happening? I am frustrated because this is a nice set of speakers and it this should not happen after only 1 1/2 years of use.


Thanks for your help!

****UPDATE***

20 minutes after writing this post, I play an mp3 and the bass works again. I am really miffed. Any ideas as to why my speakers can't decide if they want to work or not?

---UPDATE---
The sub has yet again gone out; only tinny music now (hands up in the air).

I have an Altec Lansing ACS340 speaker system with sub-woofer connected to my pc. I've had issues with the speaker volume changing and or putting out no sound at all.

We've been limping along for months by jiggling the 9-pin speaker output cable until the sound would come back. I finally spent time today trying to figure out the problem.

What I found: Due to frequent accidental bumps by feet against the cable connector, most of the solder joints where the female end of the connector is soldered into the circuit board inside the sub-woofer box had been broken loose. I had to look very closely at each pin to see where the solder joint had cracked.

The issue was fixed by re-soldering each of the pins.

Hope this can help someone with the same issue.
