2022 Prime Radio / CarPlay sound issue

Hoping for an easy answer, but… The audio in my 2022 Prius Prime Limited stopped working the other day. Display is still fine… for what it is. I can see FM and AM on the screen, but when I tap them, nothing happens. CarPlay acts like it’s playing but no sound comes out. JBL speakers. First issue like this I’ve had. Part of me wants to think it’s just a fuse, but I don’t know which one it is or where… Any advice would be greatly appreciated. I’d rather not spend who knows how much having the radio replaced… since I’m assuming that’s all built in to the display unit… Thanks!
