Hello there, I am not sure if I'm in the right forum thread but I am looking for a few recommendations to help me deal with an issue with a wireless speaker kit? My problem is related to the wireless loudspeaker set transmitter that I am employing for my surround speakers. The transmitter can never get into stand by whenever my AV receiver is switched off because my receiver will forever send out a humming sound. I've found that it triggers the wireless receivers to remain awake at the same time. That triggers my surround loudspeakers to always send a sound whilst my AV receiver is in standby which is certainly kind of annoying. I'm not sure whether there are any good solutions for this kind of dilemma. Maybe I'm going to need to physically remove the receiver from power each time. Thanks for offering ideas.
