My setup is an Apple TV 4K with a 4K HDR Monitor and a Sonos Beam.
I am using a HDMI audio extractor (AV Access 4KCVH2H) and the optional Sonos SPDIF to HDMI link to provide an audio signal to the Beam.
I used the iOS Sonos app to teach the beam to recognise the volume up and down buttons of the Apple TV 4K 6 button and trackpad remote, and everything works perfectly…..
….Until the next day when the volume control no longer works.
Each day I have to re train the beam to understand the remote control volume.
Everything remains powered 24/7 but the Apple TV and monitor sleep
What am I doing wrong?
