Have you swapped L/R at AMP’s Line-In?

Hi @jojoanddave 

Welcome to the Sonos Community!

This sounds like you have a faulty audio cable between the turntable and Amp - @buzz’s suggestion will help verify if it’s true.

I hope this helps.

I have tried switching. It “seems” like a faulty audio cable, but then how do you explain why both speakers work when I am playing off Spotify? This is only an issue for the turntable input.

Hi @jojoanddave 

Spotify plays without issue because the audio cable between your turntable and your Amp is not involved. This further reinforces the idea that it is the audio cable that is faulty, and not the Amp or the speaker wires.

I hope this helps.

If it isn’t thge cable it might be one of the connectors is bad.

Had that happen on a different brand when the RCA cable got jerked hard and the connector no longer made good contact with the tip of the RCA jack.

But Spoitify plays through BOTH wired speakers. For the turntable it only plays through one. So I don’t see how it can be a cable issue if both speakers work for one source but not another.

Hi @jojoanddave 

We seem to be referring to different cables. I am referring to the cable connecting the turntable to the Amp. You seem to be referring to the cables going to each speaker.

I hope this helps.

Ah, understood. Let me try with different cables. Thank you!
