No sound when using Airplay 2 with Apple TV on Sony XBR 950G
I have tried streaming Apple TV from both my iMac and iPhone using Airplay 2 to my Sony XBR 950G smart TV. I am getting video in both cases, but no sound.
I was able to get both video and sound before the latest Sony firmware upgrade (and perhaps the switch over to Airplay 2 from Airplay)... but that was a while ago... I only watched one movie from Apple TV prior, and that was some months ago, but without a hitch. Now I get video, but no sound, whether I try using my iPhone or iMac as the Apple TV source. (To be clear, I am talking about the Apple TV app, not hardware). I can control the volume control (slider) on the TV using either Apple device, just no sound is audible. Also, if I stream via Airplay 2 from either Apple Music or Apple TV to the Onkyo receiver that is part of the home theater system, I do get sound. But in the latter case, there is no video on the TV (of course) just the icon for whatever program or movie I am trying to stream.
I think this is a Sony issue, but was curious if anyone has any thoughts.
Any thoughts? Thanks.
