I’ve tried all the suggestions in here, turned the Dolby off, my tv speakers are off. Switched to PCM. I had to reset the factory settings on my Visio because every time I’d turn TV Speakers to Off, it would automatically switch back to on. I thought this might have something to do with the Fire Stick, but resetting the tv fixed that problem. Ive gone to Browse on the Sonos app and have selected tv, but there is no audio coming out of the Beam when on Fire Stick.
