Help! Speakers are popping with iPhone/BT

Hello everybody! I hope someone can help. I'm new to the forum.

I'm running a basic set up, Denon AV 3803 receiver with a Logitech BT adapter, playing music through my iPhone.

Everything works fine, except when I use voice text there is a loud pop from the speakers. There is also a pop a few seconds after I stop playing the music.

I ran this same set up at my old house for years, and never had this issue. Now I'm in a new place and having new issues that I can't figure out.

Any advice would be most appreciated. Thanks!

Jim
