Project Primary E (Phono) to Sonos Era 100 with RCA to 3.5: Buzzing/Grounding issue?

I’m having issues connecting my Project Primary E (Phono) to my Sonos Era 100,

I have the Sonos USB-C to 3.5 Line in Adaptor and my Turntable came with a RCA to 3.5 cord.

Everything connects and plays on the Sonos Era 100 but there is a loud buzzing sound which I think is a grounding issue? How can I fix a grounding issue where there is no option for grounding on the Sonos Era 100?

Am I missing a piece of equipment like an Amp? I thought i didn’t need one because my turntable has a phono pre-amp inbuilt and them the Sonos Era 100 already has line in connection?

Help!

Check all the connections on the turntable.

Plug the turntable into a different outlet.

Put the turntable on a different surface than the speaker.

Try a different RCA to 3.5mm cable.

Set the Source Level to a lower setting under the Line-In settings in the Sonos app.

Thank you for answering!

 

but i’m actually very dumb and just forgot to switch my turntable from Phono mode to Line-Out mode dfacepalm]
