..could be that the headphones arn't shielded and act like an antenna. Try grabbing the cord when you've got it on. If the humming goes up, it's probablt due to that.

I know, my work headset at home here does that all day! It does go away when you mute though?

Ok, so no one took notice of my post.

I did a bit of searching, and there are loads of forum posts about this problem.

Basically, the onboard sound bus is located near to the PCI bus controller, and so picks up interference (caused by the varying electric current in the PCI bus causing a varying magnetic field, that induces a current in the onboard sound bus).

A dedicated sound card is better shielded, and also "cleans up" the sound before it is output.

So you can A) leave it alone, as you said you never even noticed it until just now, or B) buy a dedicated sound card. You should be able to get a basic one for about USD20.

Yeah they're quite cheap to buy. Least we now know what causes it, cheers Callum.

I tried several different headphones and speakers.
It is a problem with the sound card. That I'm sure of.

I did. I did.

I'll be getting a dedicated sound card. Thanks for the info. [img]smile.gif[/img]

If that's case, then I would see about getting a used one. Sound is not a big factor for me since I only use it for games, so I wouldn't spend much.

I got a new soundcard and problem solved. Thanks Callum.

I do have this problem too but I just ignore it and put on some music instead. Problem solved the cheap way! [img]tongue.gif[/img]

Glad to be of service! Practicing for my new job in tech support.. w00t! :D
