Sounds to me like you are hearing interference from the video on your
Dell. Does it make icky noises when you open/close/minimise/move
application windows accross the screen? Does amaroK get noisy when there's
a lot going on visually? Does it quiet down when you close the window but
keep the systray icon open?

It may be something to do with the IRQ settings for your video and audio
systems. Ask someone for help configuring these - I can't help you, but
others on this list know about that stuff.
