I was listening to some music on Youtube when all of a sudden a burst of radio noise came through the speakers. In German. And really loud too. That wasn't the first time, as I've heard faint German music coming from the speakers in the past when no audio was being played on my behalf.

Does anybody know how that can be possible? I have a Logitech speakerset without AC-filter in it. In the past I've tried to record the music with my phone, but the sound is so low the microphone doesn't pick it up.

Anybody? Bueller?
