I have no sound. I followed the often shared advice here to take it to a friend's house that had a CEC tv. I took it to a friend's house, plugged it into his CEC Arc TV; opened the Sonos app and no Sonos setup was needed. The speaker played great. Thinking it was solved I took it home and set it up, but there was no sound again.
I've tried multiple configurations, including connecting the Arc HDMI directly into the projector HDMI port but nothing. My current configuration:
BenQ TH671ST Projector --> Display End of 18gps HDMI cable --> Source End of 18gps HDMI cable in Arcana --> Arc.
Arcana Port Configuration:
* HDMI In - Firestick
* Power - Arcana Power
* HDMI Out - Source End of 18gps HDMI
* eArc Out - HDMI to Arc
Every time I try and setup the Sonos TV app I get the CEC Not detected error. What am I missing? Did I do something wrong/miss a step, when I hooked it up to my friend's TV?
What is not working here?
