When I play audio on the sonos arc through the app, or ask Alexa to play a song, it plays through the arc for a few seconds and then switches back to the TV Audio In status in the app. My TV is off, so TV sound is not actually coming through the Sonos.
I am using Xfinity X1 box, which is connected to an HD Furry Arcana eArc adapter, which then connects to both the TV and the Sonos. Wondering if this is my issue? Any ideas?
