turntable to play 5 issues

Are any of the other options for support available where you are?  Answering my own question, only the Sonos bot.

(Select the country in the very bottom right, click the tiny flag)

Send in a diagnostic while trying to play something and see if the bot is any help at all. (Don't post the number here)

You also have a PORT and you can play the turntable through PORT? This suggests that there is a cable issue between the turntable and FIVE.

Yep, I also changed the cable, I’m starting to think it’s a problem with the Five line in.

Make sure that the plug is fully seated in the FIVE. You must push harder than some users are comfortable with, but less than full insertion usually results in only one channel.

Buzz, thank you — I’m fairly good with audio systems, but I’m afraid there’s a problem with the speaker.

Of course we cannot rule out a hardware issue with FIVE. I try to rule out the silly things up front.

Speaking of “silly” I assume that the turntable still works when connected to PORT.

When you plug into FIVE, does it acknowledge the connection?

Yes, it recognizes the connection but doesn’t play any sound. When connected to the Port, it works. The same thing happens with the CD player.

While I don’t recall any similar reports (of course there could be a few that I’m not remembering), evidence of a hardware failure is piling up. Mother Nature is never fair.

I tried with an old Bose speaker using line in not connected on sonos system and the turntable works fine

Then there seems to be nothing more this user community can do to help - you need to speak to Sonos, or the retailer you purchased from.
