Weird computer audio coming through speakers
I've experienced this before but can't remember why it happens. We have a laptop here in school and the audio is terrible through the speaker system. Plug it into the amp and the volume is very low but when you turn it up you can hear the sound of what sounds like a Spectrum 48K loading a game! Every time you move the mouse- it makes a zzzrzrzrz sound. If you jiggle the jack output it can get a little louder but still awful. Any ideas?! The laptop is a Toshiba.
