I have a pre-amp record player, bought the Sonos cord USB-C to Audio plug and connected to ERA100. I see the signal is working from the turntable into the Sonos as the bar graph is working but no sound is coming from any speaker. The ERA 100 speaker is called “Sideboard” and the device on Line In is called “Turntable”. The turntable worked on S1 into a Play 5. Unplugging the cable removes Line In as a Source on My System so obivously ERA 100 sees the device. What am I doing wrong as all the setup is seemingly ok.
