I just got a new ASUS laptop. Plugging it into a friend's stereo with a 3.5mm->RCA adapter, I got constant bursts of static drowning out the sound whenever it got a little bit of bass in it--say, an explosion or Darth Vader talking. I checked the connections and tried moving the audio cables further from the power cables, but nothing changed.
Plugging my iPhone into the same adapter produces no static. Plugging a different laptop into the same adapter produces no static. Plugging the ASUS into headphones or a set of computer speakers produces no static.
At this point, I can't figure out what could possibly cause an awful audio problem, but only with one specific pairing of source and speakers.
