I am noticing that the volume on my Sonos speaker sometimes changes on its own while music or TV audio is playing. There is no one else controlling it from the app, and I am not using voice assistants at the time.

This happens randomly and can go either louder or quieter. I am using the Sonos app on my phone and the speaker is connected to my home Wi-Fi network.

Has anyone experienced this before? Could this be related to TV remote signals, HDMI-ARC, or another app connected to Sonos?

Hard for us to tell, without the data stored in the Sonos diagnostic. It could be any of these, although the first two are the same. 

I would recommend that you 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.

CEC wouldn’t be an issue when listening to music, as the OP stated was part of the issue. 
 

I’m certainly not aware of it as a ‘common issue’.

Thanks for the suggestion. I’ll reach out to the Community Center of Excellence and share the details there. Hopefully they can help look into this further.
