Question about Denon AVR-3801 Receiver
The solution of leaving the thing on all the time would certainly work, but most of the time a buzzing sound inside a relatively robust audio amplifier is being caused by the huge transformer coil in the thing. Or wires that are in close proximity thereto.
In some ways, you're blessed that the buzzing is coming from the unit itself, and not through the loudspeakers.
