Hi,
just got my sonos port to connect my turntable to it. But can it be that the port doesnt have a GND connection? I definitely need Ground for my turntable. I mean, Sonos is advertising this as the optinal way to connect turntables and then forget the GND attachment?

Hallo Marc and welcome to the german community,
sorry, Port does not have a ground connection pin and I was told that we probably don’t need GND with a preamped signal.
Check if your turntable has a built-in preamp like the Pro-Ject T1 Phono SB Turntable. If your turntable does not have a built-in phono preamp, you will need to first connect your turntable to a phono preamp, and then connect the phono preamp to Sonos Port (Line in).
On a phono preamp you will usually find a ground connection pin.
Please check:

In our english community I found experienced users talking about GND here. I’d suggest asking there.

I have the Pro-Ject T1 with preAmp. So you mean GND is not necessary when using the PreAmp?
Yes, this is what project-audio says about ground wire and built-in preamps:
Project-Audio
In case your amplifier does not have a ground connection pin, most likely it does not have a phono-input (phono-preamp). If this is the case use the turntables built-in phono preamp or an external phono-preamp
When you connect your Pro-Ject T1 to your Sonos Port ensure it is outputting to Line-out.
Please contact Project-Audio for more information about your turntable and mind the links I posted above.
Best regards
