I've searched everywhere for info on this and it seems like the only info put there is to setup with a receiver, which I don't use.
I found another way thru Alexa to add speakers etc for the firestick, but maybe it's just for Bluetooth speakers and not wifi speakers, because it can't seem to find any of my other speakers other than the arc and sub.
Does anyone know if 5.1 can be done with sonos and the firestick? Seems like a complete waste if it can't, but i refuse to believe i can't do this. Anyone?
