I can see my home mini streaming on my phone, but no sound comes out. It has been working fine for a year now. If I cast from my phone, it works fine. I've done all the resets. Even reloaded tunein, but still nothing. The google assistant is working fine. No issues finding the radio stations, just no sound comes out?
That certainly hasn’t been easy for you — let’s check what’s going on.
A few questions: are you getting the same result when playing from iHeart Radio or playing music to your speaker? Are you getting any message or it really doesn't play anything? Could you please try rebooting your speaker and router to refresh the connection?
Let us know how it goes.
