low sound until 80+ - port and pro-ject debut carbon turntable

I have just unboxed and connected by pro-ject debut carbon turntable (which I understand has built in pre-amp) to my port.

i have zero/low volume until i get to 80+ from my connected speakers (arc and ones) and then I get humming as well. 
i previously had a cheaper Sony turntable which worked fine under the same set up and have been through every thread on here and nothing working. 
Just wondered if anybody has come across anything else that might work? 
Or is time to try my luck with uk customer services?

thanks in advance!

Are you sure that the turntable has a preamp and that it is operating? Your symptoms suggest that there is no preamp or that it is disabled.

Try this...in the Sonos App (for the Turntable room) go to Source Level and select Level 10. You can adjust downward to get the input level that works best.

Thanks AjTrek1. Already tried that - no change! Tearing my hair out

Also, there is a toggle switch to select pre-amp built-in. Set it to “Line”

Did you purchase the Sonos addition (via Sonos) of your turntable which has a built-in pre-amp as others may not.
