Question

Line In Source Level setting no longer has any effect

I have a Pro-ject turntable connected to an Era100 stereo pair + Sub mini via the OEM Sonos USB adapter. Audio is passed from the turntable to my setup just fine. The problem: the setting for Line In Source Level no longer has any effect - I can change it from Level 1 → Level 10 with no audible effect. Also, if I change it to anything other than Level 1, if I quit the app then reopen it, the Source Level is back on Level 1. No other Level settings “sticks”. 

Prior to this, I was using the same turntable and adapter to connect to a Move 2 (months ago). The Source Level control worked just fine then (I had to keep it set to Level 7). Now, several app updates and firmware updates later, it’s not working - I’m not sure when it stopped working.

A few people are reporting the same issue on Reddit. Is this a known issue?

Yours is the first post I’ve seen. I’d certainly be tempted to reboot the Sonos device your line in is plugged in to, but if it continues to act oddly, I’d submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, their lawyers get sensitive about GDPR.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

If there is an issue with the Sonos, having hard data may go a long way in resolving the issue.

    This is resolved. After the app + firmware update a couple days ago plus Sonos and router reboots, this is working again.

      The fix for the Line-in settings was mentioned here in the Community post for the latest app update, but helpfully not detailed in any meaningful way in the app release notes.
