I recently purchased a Pioneer PLX500 with built in pre-amp, and have followed all the connection tips that I could find on the sonos website as well as other sites, but I still can't manage to get music to play through the speaker. All I seem to get is a humming/buzzing sound if I turn the speaker volume right up. I have been using the Play 5 as part of my Playbar and Play 1's set up for over a year without any issues, so I've even tried factory resetting it to completely disconnect it from the rest of the group. I've got the switch set to Line and have set up the changeable line-in settings (to the best of my knowledge) and I can get my android phone to play music via the 3.5mm jack / line-in function, but when I connect my turntable again.... nothing. Just humming and buzzing. I've taken the turntable back to the place of purchase and they tested it there for me and it played fine, so I have ruled out any issues with the turntable itself. Is there some simple setting I could be missing on the Sonos controller? Getting desperate and fed up now!
Cheers in advance for any assistance you can provide!
