Unwanted static/sound from speakers

[learninmypc]

It started a few days ago. To my knowledge,I've made no changes to sound settings. No caution/exclamation marks in Device manager under sound.I've run full scans,clean. Rebooted & even shut it down completely. It does not happen ALL the time, just sporadically. Any ideas? TIA.

Im guessing you may need a ground loop isolator (http://www.amazon.co.uk/hq-CAR-NF01...76778008&sr=8-1&keywords=ground+loop+isolator), but am not sure... What speakers are you using?

First off, I've had this W7 since December & have no problems at all.
My External speakers are Logitech. It has a BIG woofer & 5 or 6 other speakers.
I'll try to find the specs on them & post them.I've had the speakers for a few years & no problems.
"EDIT" The ones I have http://www.meritline.com/logitech-x...ource=fghdac&gclid=CMnturHdhbkCFWNxQgodmW0AiQ
They came with my XP a friend gave me.
ALL the same, the 3 top ones here

I have this issue with my headphones. I unplug them and it goes away, but it is annoying to always do this when I hear the static (often).

I do hear it with my ear buds in,but am so tired, I sleep anyhow. Perhaps someday it'll quit. I'm going to re check the connection later today. If nothing else works, I'll live with it.
Thanks for your input.

In post # 3 I showed the speakers I'm using. The static or whatever it is hasn't stopped so I'm wondering if I might have them plugged into the PC incorrectly. Here is the best shot I can get of the
inputs

I'm now wondering if the top right one plug (pinkish) should be in the bottom left input? Vertically, it says c/sub. ???
Blue is input
Black is Rear
Limegreen is out&
Grey is side.

Ok, I'm confused as always This is the pdf Manual http://logitech-en-emea.custhelp.com/ci/fattach/get/382880/0/filename/x530_Manual_AMR.pdf
I'm sure I hooked it up correctly to the speaker, but I'm kinda doubting the pc connections.
Any help is appreciated.

"EDIT" I did dig out my alternate set if need be. Not as loud & good as this current set up,but.

 

[learninmypc]

Absolutely no guarantee, but how can this be? Upon closer examination, I found I had a couple RCA plugs in the incorrect sockets. I've changed them & so far no unwanted static/noise so why didn't it happen sooner? My fingers are crossed the problem is fixed, but I won't know till maybe tomorrow?

Oh well, no matter what I did, they still have the noise so I removed them & have my alternate set hooked up. Thanks to one & all for helping. Maybe Santa will be nice to me this year. (y)
