buzzing/hissing laptop (headphones)

Hello,

plugged-in laptop buzzes/hissing through headphones, when using heavy 3D applications. Buzzes when switches to headphone jack (when plugged in).

Unplugged from power supply doesn't buzz. Normal use (browsing, movies..) doesn't buzz.

Even with sounds to 0, same buzzing is still audible.

could this be cause by coil whine?
