Joerg, I also tested this by lowering Mono to 72 with alsa-mixer on my A6 OM2009 Test4 after reading Warrens mail, and I now no longer sound like sitting on a motor lawnmower during a call. Maybe this is something different than the Buzz Issue, but it improves sounds for the other party a lot. This btw is in The Netherlands. After reading that less than 5% of the owners are hit in practice by the Buzz Issue, I was pretty surprised to be one of them. But now it seems the noise is not due to the Buzz Issue?
