speaker buzzing

post #1 of 2
Thread Starter 
i have some m-audio monitors and sub hooked up to the desktop in my sig and it works perfectly. i also have a surround sound system in the living room and sometimes i take my machine in there and hook it up to the tv and the sound system and watch movies, and it works perfectly

when i try hooking up my laptop (compaq presario v2000) to either of these systems, it makes an insanely loud buzzing noise, not just a hum, its loud enough to ruin the movie. i asked someone at guitar center and they said the headphone jack in laptops isn't meant to power such good sound systems and it just messes up. seems like it could be true because the laptop works with cheap logitech speakers. is that right?

i recently discovered that if i unplug the charger, the buzzing goes away. i thought that was weird and wasnt sure why? is there any way to fix this without having to unplug the charger, because the battery only lasts about an hour

Yeah, the charger causes the problem. It has something to do with the electrical current. Buy shielded wires for the speakers, also the laptop does not power the speakers. That comes from your wall.
