Sonos Arc here.  Pretty much at my wits end on setting up my Sonos Arc using Trueplay.  Trueplay worked fine right out of the box.  Since then have rearranged some furniture in the room and wanted to run Trueplay again.  Now has background noise problems when I try to run it.  Everything turned off, everything has been rebooted, access to my iPhone 14 microphone is fine, but every time I try to run it there is always a background noise error message. Nothing is running.  No one is making any noise.  Very annoying.  The one thing I have not done is to call Sonos.  That will probably be my next step.

Did you try removing your phone case and blowing out the mike port?

Before you call, run trueplay again and a soon as it finishes submit a diagnostic, it may save you time.


It seems that could be a problem with the phone mic. Could you try with a different iPhone? Just to rule out things. 


Hi ​@Mike2012 

Welcome to the Sonos Community!

Sorry to hear of the problems you’ve been having with trying to TruePlay Tune your speakers. In addition to the advice you’ve been given above, please also ensure that there are no Bluetooth devices such as Air-Buds connected to your iPhone at the time of TruePlay Tuning.

I hope this helps.


I hadn’t tried that yet.  I do have one Bluetooth device connected so I will disconnect that and try again.  Thank you for your help.
