Does anyone else have the problem that there is always a loud popping/crackling noise when the line-in is plugged into the audio source or when the plug is touched? I know this from the more expensive hi-fi amplifiers, where it always occurs when the audio source and the amplifier are not connected to the same earth and a ground loop is created. But the Edifier has neither an earth connection on the power plug nor an earth connection on the cabinet ... How did you solve this problem?

I hear a crackling sound when the volume is not muted and I touch the line-in cable. But this is normal and happens with every amplifier. But when I switch between Bluetooth and line-in, there's no crackling or anything else.
