I am experiencing an audio routing issue with my Sonos surround setup that only started happening recently after a recent software update. Up until recently, this setup worked perfectly.
My Setup:
- Soundbar: Sonos Beam (Gen 2) connected via HDMI eARC.
- Surrounds: Stereo pair of Sonos Era 100s.
- TV: Sony W800F.
- Source: Apple TV 4K connected to the Sony TV via HDMI.
Whenever I switch on my TV, I need to manually go into the apple audio output option, select Sonos setup, and everything works great—audio plays perfectly through the Beam and both Era 100 surrounds.
However, the moment I press any button with the Apple TV remote (changing apps, volume controls, or pausing a video), the audio output automatically changes away from the Sonos system back to "Native/TV Speakers". Because the TV assumes the Beam is the native speaker, I still get front audio, but the Era 100 surround channels completely cut out, and I completely lose the ability to control the volume using my Apple TV remote.
To get surround sound back, I have to manually go into the Apple TV audio menu and select the Sonos system again, creating an endless, frustrating cycle.
