I recently setup my 5.1 Sonos audio system in my living room. I was using a Yamaha TSR-5810 stereo receiver, and Bose 5.1 audio before. Per Sonos instructions at setup, I disabled the audio speakers output on the receiver. Watching cable TV, and Apple TV thru my HDMI port #1 sound great, with the stereo off and enabling HDMi pass thru. The problem is, when I turn on the stereo to select HDMI port #2, to watch my Amazon Fire TV, then shut off the stereo, I get a picture, but no sound on the Playbar. Do I need to connect the Amazon Fire TV directly to the TV in order to get sound on the Playbar? Is there something else I need to disable/enable on my stereo to switch HDMI stereo inputs for other devices such as a Blu-ray player, or Fire TV, to other than HDMI #1 and still get audio on my Playbar? Thanks for any help. I’ll try the tech support office next.
