Wireless audio sync not working
After trying to use Apple TV wireless audio sync several times, it has stopped working at all.
It used to work, at least for a little while, when I would play music from my Apple TV to my Sonos Ones in stereo, while also out of my sound bar through HDMI (all in the same room).
Now even when I run the sync calibration, I get an audio delay of about 300-500ms between the Sonos and the sound bar.
Is there a fix for this?
