When on AC and "Speed" selected the sound out gets screetch and fuzz sounds from the graphics card. The screeches, fuzzes and buzzes correlates with screen activity. It's unpleasant to listen to music while working. If unplugged it's fine. Does not happen on "Stamina" (Intel Graphics).
Hmm... this seems to happen when I run the sound through an old NAD. If I run it directly through the power amlifyer it's better (but not for parties). Strange.
TIA,
