So I originally was having problems using the stereo pair of HomePod minis with our Apple TV 4K. (It would lock up after a few seconds of playing). The latest IOS update 15.3 seems to have fixed this problem. However, the sound coming out of the speakers sounds so unnatural and almost like it coming from inside a tin can with an echo . If I connected to that same stereo pair from my phone and play music the sound is fine. Any suggestions?
