Hello,
I see that this has been posted before but I can’t seem to find a response that works for me. I have a U-Turn Orbit turntable going to a Pro-Ject preamp feeding a Sonos Port. I cannot for the life of me get the Autoplay to work consistently. No problem choosing the source in S2 but dropping the needle doesn’t trigger autoplay. I have tried adjusting the line-in gain from Level 1 all the way through to Level 10 and it still won’t trigger 9/10 times. Curious if there is a solution as I had the exact same problem with my Sonos Connect. I have tried with different preamps and even a different turntable with the same results.
