Hello, first sorry for my english, it is not my native language. I bought Harman/Kardon SoundSticks Wireless, that work very good with my 2015 iMac. But I find out one problem. When I am not playing any music or I am doing some work on my iMac (when speakers are idle) and suddenly I start some music, there is one annoying "CRACK" ("POP") before they start playing that music/sound.... When playing they’re fine, but that one "crack" after longer period of idle status of speakers makes me angry af. Any help? Thanks!
