It appears to be cured by removing the earth cable from the amp plug.

Yes, its just plugged from the headphone jack on the back of the computer. Changing the sound on the computer doesnt affect the volume of the interference. Im thinking its some sort of grounding issue as the noise happened when amp was plugged into laptop but stopped once the laptop was unplugged and running off the battery

So it also makes the noise when plugging a laptop into the amp. But stops when you unplug laptop from the wall.

When i disconnect the inputs then the sound goes away. Also the amp was fine when using it with my old pc. Touching a wire to the cases of the amp and computer doesnt seem to do anything either....

Hi, im wondering if anyone can help. Ive recently bought a new desktop pc and im getting a lot of nasty noises (screetching, crackly noises) from my speakers when the amps turned on. It had stopped doing it but its back with a vengeance. It even seems to go through the vga cable to the tv then from the tv via phono cables to the amp. Ive tried installing a sound card as originally the pc just had onboard sound. Ive also tried a cheap usb sound card. Ive tried swapping power cables and plugging everything into the same socket. Its driving me mad! Im going to try and get another psu to try to see if that stops it. Ive seen you can buy separate DACs, would that stop it? Thanks in advance for any help!
