Home theater hum when source device is off

[Rggmiranda]

Hi, I have the following issue, I leave my home theater connected to my pc, right now I'm using a bluetooth adapter, but its the same anyway, it produces the same inconvenient. whenever the device turns off, the HT makes an annoying buzzing, so I have to turn it off, which is not excactly comfortable, so is there a way to fix this? maybe some caps and resistors or something like that?

Um sorry didn't quite get all that. What's blue tooth got to do with anything. Can't you just turn it off if not using it. Amplifiers may buzz a bit if turned up with no input.

You may have an earthloop problem somewhere
I get the same wthing with my PC connected to the amplifier, I just unplug the PC
