I have my turntable (Pro-Ject: T1 BT) plugged into the Port and when playing a record the autoplay does not start.
However, I can go into the Sonos app and select manually Line-In as the source and the record will play into the room to my Beam.
I have rebooted the system and no dice. Pretty frustrating that Autoplay doesn’t work and having to select the source manually every time.
