Okay so I have a Toshiba Satelite Harman/Kardon with Windows 7 i don't use because when I try to output audio through AUX it gives a high pitched wining noise unless I plug and aux cable in and don't plug anything else in it. Is this hardware or some other isssue? Thanks in advance and the computer is for music has a custom home audio system that hooks up to it. (3000w)

What happens when you use another form of connectivity, such as HDMI?

Well the way the system is system it's strictly aux, Have not made the conversion to be able to run HDMI as it's a decent amount of work. Not sure if it's making the noise due to it lacking a hardware ground or what.

Is it sort of a hum? It might be interference from a ground loop. In that case you need a audio isolation transformer.

Okay, I see there's no (or very little) flexibility In your setup.

Have you changed the Aux cables, perhaps to better/more expensive set and/or disconnect everything and reconnect right from scratch? Sometimes this can make all the difference. @"Skullmeat" has a very valid point too, I'd certainly be looking Into that.

Yes I have re-hooked it up, used different aux wires, My volume on my computer digitally is consistently rapidly jumping up and down about 1-3/100.

Has It functioned properly at any stage? Also, have you updated to the latest audio driver for your PC?

Not sure was given the computer and yes I updated it when I took it out of storage and everytime after.

I'll state the obvious here. Do you have another PC (If not, one that you can borrow from a friend for the Interim) just to see whether the Issue Is In fact PC-related?

I do have another computer, and that's the thing is it only does it on the Toshiba not the HP, I honestly think it's ground loop and if it is how would I fix it?
