Problem must be something else.
Cannot tell. Booting OpenBSD on this machine there is a very audible "click and crackle" when the driver attaches as if there is a huge DC offset. Afterwards there is very noticeable permanent noise (a bit higher than pink noise, a bit lower than white noise). No idea. What made me wonder is that there is no noise when booting windows on that same machine. No idea here. Does not matter. I can live with that. -- Christian
