Buzz sound when moving my mouse !

[GoustiFruit]

Hi,

I just build a new unit and installed PCLinuxOS on it. Problem, I have a constant buzzing sound whenever I move my mouse and whenever anything is moving on my screen: a simple web page with some animation makes my speakers buzz. Even when installing PCLinuxOS, the progressbar animation made my speakers buzz !? Every time something moves on my screen I get that annoying background  sound 

Can anyone tell me what to do, what to check ?

you need to reconfigure your sound setup.  that problem annoyed me for a while many moons ago.  alsaconf may sort it out for you, else use the pclinuxos control centre.

Its probably an AUX or MIC input thats enabled and causing noise problems. Usually this happens with onboard sound, which tends to pick up a lot of electromagnetic interference from the PC.

You may have been hit with the vuvuzela virus... buzzzz buzzzz...(just kidding)  If the above don't work then you might have an irq conflict and might need to play with some bios settings. I've had this happen with Windows but never in Linux.

I tried muting all possible channels, nothing works. Only when I disable the onboard chip in the BIOS, but then I have no sound at all... ARGGHHH, I think I will have to return that hardware, motherboard or PSU, there must be something wrong in there

Do you have an Athlon cpu?

If so, try installing athcool from synaptic and then typing 'athcool off' in a terminal.

If this helps, I have a script for rc.local that will do this automatically at boot.

Mebbe the mouse has become sentient and is talking to you    (I mean it is using Linux as its "commander")

@mikkl: I have an Athlon II X3 but when running "athcool off" it tells me:

Code: [Select]

no supported Chipset found. nothing changed.So it doesn't help

[luikki]

can you check if the buzz persists if you run a live cd?
if it does, it could be caused by wrongly seated motherboard or backplate... or a failing  power supply...

Bummer.  After much digging into the same problem on my machine, this was the only solution that worked for me.  Something in the power management logic (I assume) causes the problem.

Though a bit old, some of the steps in this link may help:  http://www.daniel.nofftz.net/linux/Athlon-Powersaving-HOWTO.html#athcool

The point, however, is to turn OFF the powersaving mode and to see if that helps.

You might also check your BIOS settings to see if you can adjust power saving features there.  I'd start with a complete disable and see if that helps and then tweak from there.

I played with about every options in the BIOS related to power management, and saw no improvement.

I tried running PCLinuxOS from a liveusb, same thing.

I think the motherboard may be in cause, or less probably the PSU. I will contact the vendor to see if I can have a replacement.

For information, the case is a Silverstone SG05 and the mobo is a Zotac 8200-ITX. By the way, the image is choppy even with nvidia proprietary drivers: is KDE4 supposed to run well with an integrated gf8200 ? I have another system with a gf9300 and it's very smooth...

One thing I just noticed is that for this board only AMD CPUs that are 65-watt TDP are recommended... And mine in 95-watt TDP... Do you think it is the reason of the problem ? I wouldn't like to buy a new CPU is the problem is the motherboard

You could try making sure that "Legacy USB" (or similar) is enabled in the Bios. Not sure if it'll help you but.....
