Buzz in speakers when using audible app

I just got a 2019 with the jbl audio system. The speakers sound fine when listening to music or if I'm listening to an audio book over Spotify. However when I play the audible app ( through Bluetooth or aux cord, I can't get the USB to work) the speakers buzz when the narrator says words that begin with the letter S. This is true with any book I play on audible in the truck.

The noise sounds kind of like coins vibrating in a tray next to a speaker. I know it is coming from the speakers as I can isolate it in each speaker using the fade/Ballance.

I know this is a long shot but does anybody have any suggestions. Thanks

 

I think it’s an Audible thing. I get a weird buzzing on my headphones with Audible when I raise the volume high.
