Hi, How do connect a turntable ground wire to Sonos port? I have a turntable (Dual 429 CS - https://hifi.dual.de/en/products/automatic/cs-429/) that has a ground out, but Sonos port does not have a place to connect that ground out. Any work-around this? Has anyone come-across this issue?

Turntable ground wires are usually connected to the preamp, PORT does not contain a preamp therefore PORT does not offer a ground lug.

I have not purchased the port yet. This is a pre-purchase question as usually there is a ground connection in an amplifier, but in this case like you mention I may not need a ground to the port and hopefully there will be no humming or buzz in the sound. Thanks again.

it looks like your turntable has a preamp built in. Make sure you use the ‘audio port’ RCA ports on the turntable, not the phono.
I have the same issue. I just noticed the buzz on my music hall turntable that’s connected to my Port. It has a built in amp, and I connected the cables from the audio ports to the Sonos Port. There’s also a phono/line switch on the back of the turntable that I switched to line. Is there another way to ground that wire on the Port end? Thanks!
You would want to ground to another device, such as a receiver, or even the wall, but not to the Sonos Amp.
