I have a Project turntable running through a vintage Pioneer Receiver—SX 828, and just recently added a Sonos Port. It works great to stream from our phones through the Pioneer and also the Sonos 5 and Era 100, but when I try to play vinyl, I can’t get anything out of the Sonos side. Still plays great through our Pioneer system. For the Port, I have the out going to the AUX to stream, and then ran RCA’s from the Tape Recording to the Port’s in, but still nothing. The app shows that my line in is a turntable, but it never shows anything playing, so I am clearly not setting something. Have confirmed that this receiver has a signal out for that Recording connection, so think it is something to do with how I have the Port configured. Open to any suggestions.
