(1) Sonos ARC connected via HDMI to Arc port of the TV => works great.
(2) Second sound source, that I convert from Optical to HDMI using the Sonos Adapter. If I connect this via HDMI to Sonos ARC (and disconnect TV), it works great.
Question => Is there a switch/splitter that I can control with a remote without having to switch the Sonos ARC cables in this setup?
TV only supports ARC. I connected the second source to the TV, but the TV does not recognize it.
