Specs: Windows XP
I observe noise in right speaker. The noise remains regardless of playing audio or not. If I reduce right speaker volume to zero, I can listen audio in left speaker without any noise. I have dual boot system (Windows XP and Linux). The noise appears in both OS mode.

Got a pair of headphones you can try? Temporarily unplug the speakers from the soundcard & plug in the headphones...still have the noise on the right side?

I would like to add some more observations:
The noise appears in headphone as well as in external powered creative speakers.
Sometimes noise randomly goes off. But reappears after some time or after next reboot.

"The noise appears in headphone as well as in external powered creative speakers"

But were the headphones plugged into the speakers or directly into the soundcard?

OK, that rules out the speakers & since it happens in both Windows & Linux, that should rule out a driver issue. It would appear to be a hardware problem then. Have you made any recent changes?

Did you unplug the speakers when testing using the headphones?

Yes, speakers were completely powered off while using headphones.
I have added 1GB DDR RAM some six months ago. Do you think, this can cause the noise? Anyway, I will repost after removing the extra DDR RAM and testing noise.

"Yes, speakers were completely powered off while using headphones"

I believe what OtH was asking was, did you unplug the speakers from the soundcard when testing using the headphones?

Yes. Speakers were isolated from soundcard too.

Hi, I have encountered similar problem and just managed to solve it.

Got myself new set of speakers with a better freq. range than my old one. However, there is some noise "Ta ta ta ta .. at times when the harddisk is running"

Finally solve it by taking the power for the speaker from another power point in the house instead of from the multi-socket sharing power to the CPU, monitor... printer... etc.

So try using another power point to remove the noise. Good Luck.

Hi ya,

Its me again, apparently after further investigation, you have to make sure the thing that controls the volume of the speaker does not touch the CPU . To be safe, as little of items belonging to the speaker to touch the casing of the CPU. Ops...

Cheers !!
