After 4 calls to Sonos, the first 3 reps worked hard to diagnosis issue and couldn’t figure out what was causing this issue but the 4th rep advise this is the new functionality after last week’s software update.
Here’s the problem. I have a Sonos Arc system connected to my home theater TV. I never use that system for anything other than watching TV as we have other Sonos speakers for listening to music.
Starting last week when I turned on my TV, I was getting no sound from the Arc regardless of the app I chose on my Apple TV device and I couldn’t figure out why. Lots of restarting devices and troubleshooting. The only way I was able to get sound back after hours of trying different things was to use a Surround Sound test app that sent individual sounds to each of the surround sound speakers and subwoofers and then the sound would work fine again until I paused the TV or turned off the TV, then I would loose sound again. When I would look in the Sonos App on my phone, it would show the source for the TV was changed to a radio station. I never listen to radio on that device, why was that happening?
Evidently with the new software, TV input is dropped when no sound is coming from the TV and it picks maybe a last radio station played???.
Now evertytime I want to watch TV, not only do I have to turn my TV on, I have pull out my phone, go to the Sonos app and select the speaker Arc and then change the input to TV. This gets old, especially if you just want to pause something and come back to it later after eating or a bathroom break.
