Windows 7: Mouse noise

11 Jan 2012   #11

XP SP3 32bit, Vista HP 64bit, Seven Pro 64bit

The "buzz" is electronic noise picked up by the soundcard.

This can sometimes be fixed by muting any sound sources you are not actually using, particularly the microphone. If you sometimes use a microphone either be sure that it is always plugged in and turned on, an empty microphone connector plug will pick up noise and amplify it, or simply mute the microphone except when you want to use it.

Go into the soundcard control panel or the Windows Audio Device Control Panel (the Windows Mixer) and mute all sound sources except the "Play Control" which is the master volume.

In Win 7:
Start -> Control Panel -> Hardware and Sound -> Sound -> Manage Audio Devices

Click on Speakers -> Properties

On the Levels tab you can mute the various sound sources.

Never know this on a desktop before mainly laptops. zBobG is right though, System sounds and or line in generally kills this.

soz, yes, should have mentioned, all superfluous i/o's muted - mouse noise on speakers and phones of both s/cards. All audio leads are pro qual (OFC/gold)

i've been building pro studios since the days of the STFM, and pro audio PC's since '98. Generally i'll use nVidia cards because i've never found a solution to the mouse-noise prob with ATI cards, but my main studio machine is also for vid editing and 2D/3D animation so I needed something to handle 4 monitors with a view to adding 2 more monitors this year hence i have a 6950,... and a buzzy mouse

Are your sound device(s) and your mouse possibly sharing an IRQ address perhaps?

If they are it'd probably be the cause, and you could simply attempt to reassign interrupts...
