Question

Sonos Voice Control false activations on Beam Ultra since Sonos 27

Hi, since updating to Sonos 27 and setting up my new Beam Ultra, Sonos Voice Control regularly activates the microphones when nobody is saying anything.

 

Setup: Beam Ultra with two Era 100 as surrounds, connected over HDMI eARC to an LG OLED C5, with an Apple TV 4K (2nd gen) as source. Sonos Voice Control is the only voice assistant. The microphone switch and the voice button are both on.

 

It happens mostly while watching TV, and it started right after Sonos 27 and the Beam Ultra. Is this a known issue, and is a fix planned?

 

Thanks!

I’d suggest, after experiencing one of these ‘false’ activations, you submit a system diagnostic within 10 minutes, and call Sonos Support to discuss it. Do not factory reset any units. Also, don’t post the resulting diagnostic number here.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution, particularly about what the SVC system ‘heard’, in order to activate. To my knowledge, yours is, so far, the only report about this behavior, so it might be a local issue, but them having hard data of what your system is experiencing might go a long way. 

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.
