Hi,

I have had this issue for a while now, but I have a soundbar (Harman Kardon Enchant 1300 + Sub), standing 2 meters from my Deco M9 Plus (ethernet backhaul). Every time I am streaming music via Wi-Fi (Chromecast) to my Harman Kardon Enchant 1300, music keeps cracking and distorting every now and then. I switched off the Deco M9 Plus, and the soundbar connected to another Deco M9 Plus (also ethernet backhaul) in another room, and is no longer suffering from interference. What do I do?
