120V 60Hz, everywhere. You plug in an AC adapter that changes it to 12VDC
or 5VDC, with some ripple of course. If this is charging a battery in your
laptop, the battery acts like the largest capacitor in the universe, and
should filter out all the ripple. If it doesn't, and some gets into your
sound card, then Dell has a very poor power supply design. Even so, all
that should get to the sound card is 60Hz humm. Does the noise sound like
hummmmmmmmm?
