Greetings, for years my 2.1 Blueberry SW-M30 50W Woodpecker would occasionally start buzzing for no obvious reason. The only thing that makes it buzz decrease is turning up the volume and treble on the speakers manually (i decrease the volume on windows after that).
It's only the satellites that are buzzing, and sometimes the buzz sounds "electric".
