Buzz from mouse in speaker

@dundeyr 

My best guess is that the source of the problem is coil whine from the motherboard. i have tried replacing the PSU to no effect. 

I think you're right.

Some Asus motherboards do exhibit this kind of behaviour, and no doubt other makes must do too.

I can however not hear it in a pair of headphones.

My Asus PC does the opposite.

It's clean through speakers but has that faint ghostly interference through headphones.

It´s also transfered if i connect from the onboard motherboard audio card straight to the amp.

Have you tried using a dedicated soundcard?

This is something I intend to try once I can figure out how to install it into the PC.

So many different cards, so many different motherboard sockets ...

I use Lenovo Q190 2012 model. It was made actually as a streamer, because it's DEAD quiet and has SSD to make it even more quiet. 

Recently installed W10, because W7 not in support anymore.

Has it evaded you?  Computer sound is noisy.

Enjoy.

Next time say it this way, “Buzz in speaker from mouse.”

I didn’t want to read your post at first because I thought you had a live mouse in your speaker making noise.  Ewwww.

Anyway, what they all said.  The computer is a noisy source.  Ditch the computer and hire a band- or build/buy a dedicated music server.

Hey, I just realized why speaker ports are so high off of the floor- so mice can’t get in.

sorry i didn't realize that to kill the buzz from mouse in the speaker, you need to set up a mouse trap.
