=A0
It could be something simpler as well, some signals that are simply
being coupled onto analog output.

To say any more you need to find which driver is causing this. Mike's advice is the start; find out which drivers coldplugging loads, then
e.g. load one at a time manually. At some point you should get the
noise. Then dive deeper into that particular driver case.
<= /div>OK, how do I find out which drivers coldplugging loads?
