I don't have the B&O sound option, however, I do hear buzzing during bluetooth phone calls and some AM radio broadcasts. It sounds like a blown speaker/tweeter, however, that's another issue.
The issue I'm having is rattling in the driver's side door area while driving -- esp over bumps. I have a copy of the Bentley manual on CD which includes all current Audi TSBs, and there are several TSBs for 'noise' and 'rattling' issues. One known issue is the cover for the fuse panel. The wrench for the sunroof can vibrate and the cover itself can also vibrate causing unwanted noise. The solution is to use felt tape under the wrench and near the mounting spots on the cover. I'm going to try this tonight to see if it helps.
The Bentley manual is great, by the way. I had it for my last Audi and it proved very useful for diagnosing problems, etc.
