I have an Altec Lansing speaker set, and randomly (even when they are not plugged into anything) they make sounds. The sound is the same, even when the volume is all the way down. Can some help please.

Thank you

When you say not plugged into anything, are you including the AC power as well?

No, they are plugged into the ac, There is nothing on the 3.5mm jack. I have made sure the connector for the 3.5mm is not near anything as well. The sound is like a crackling and then suddenly there's a massive noise that doesn't go down with the volume. The noise is like a drone.

Check that your audio cable is not near any of your power cables. You can end up listening to 120 Hz that way.

They are pretty much next to each other

Audio cables crossing an electrical wire should be done at a 90 degree angle. Running the 2 wires parallel to each other is the worst configuration for interference.

Thanks to everyone that helped, it is all good now, my subwoofer with was directly underneath the plug socket.

Thanks Again, is there anything I could do on this forum to repay you guys?

This solved my sudden and mysterious static issue as well!

About a week ago I organized all the TV, PC, etc., wires by bunching them together. That's when the static started coming through my PC and TV. After reading your post I separated them and the static disappeared.

You saved my sanity....THANK YOU!
