+"How do I eliminate the buzzing noise from my speakers or headphones that occurs only when my system is connected to AC power?
+Ensure that both the computer and any external speakers are plugged into the same outlet or power strip. This should eliminate or minimize the buzzing associated with a ground loop. You should not assume that all outlets in a single room are on the same circuit. Outlets may be on different circuits, even when they are close to each other. In studio type situations where buzzing associated to a ground loop is unacceptable, an isolation transformer can be used. An isolation transformer should eliminate the problem, but is typically expensive. While a three to two prong wall outlet adapter (removing ground) will eliminate the noise, for safety concerns this solution is definitely not recommended. "
