Hi John and all Thanx for all the help! The problem seems to be solved now. There seems to be some electric interference coming from an electric fence nearby. Connecting the amplifier to a different socket solved the problem.

I still think that the problem probably lies with a power supply that is not properly shielded.

I'm asking because if you put a power supply on top of an amplifier, it will make all of those noises. My best regards!

Like the sound you get from a fax machine or when any kind of receiver picks up the sound from a computer. -----Original Message----- From: pc-audio-boun...@pc-audio.org [mailto:pc-audio-boun...@pc-audio.org] On Behalf Of DJ DOCTOR P Sent: 13 December 2008 09:52 PM To: PC Audio Discussion List Subject: Re: Laptop making strange noises Hello, Is it some kind of a humming noise or it is a bussing sound? Either way, it is all coming from the power supply. If the power supply is weak and doesn't have enough amps of currant, that thing will make a lot of noise with USB audio devices. Call or go by the store and see if they will upgrade the power supply for you. My best regards!

She had an HP before and had no such problems. It also sounds to me like a power supply problem. -----Original Message----- From: pc-audio-boun...@pc-audio.org [mailto:pc-audio-boun...@pc-audio.org] On Behalf Of DJ DOCTOR P Sent: 13 December 2008 07:26 PM To: PC Audio Discussion List Subject: Re: Laptop making strange noises Hello, The problem may be with the power supply itself. If the power supply isn't regulated properly, it will make a lot of noise through your sound system. Where did she get this lab top from? You and or her may wish to start there and see if they will replace her power supply with a better one. My best regards!
