Arc microphone constantly turns off and off by itself

johnnydrama32 et al

try this w/ both sonos voice control and alexa  loaded

go to system, hardware and turn off “touch controls”

give that a stress test…

I have the same issue on the Arc.  I ordered the Arc/Sub/2xEra300 set 08/19/2023 direct from Sonos, and have it hooked up to Alexa voice control.  Mic toggle goes on and off on its own making a chime sound each time.  I have it hooked up to Home Assistant and I can see it happening between 2 to 10 times per minute.  I think it only happens while the Arc is playing something.  As @hogan1 suggested, I turned off touch controls for the room and it immediately stopped toggling.

Will be sending the system back on Tuesday - not my job to beta test for Sonos.

since last night when i turned off the “touch control”, the arc muting problem stopped and the alexa and svc  worked perfectly - no issues

‘sparring - what about your alexa and svc?

Nice! That works and can still use Alexa. 

I have my broken ones boxed up, but I spoke to someone at Sonos yesterday who's based in the US. He felt it was likely a hardware defect in our units. I'm sure that fix works but then you can't use touch controls. I don't want a device that I can't resell down the road because it's defective.

I didn’t test SVC, but confirmed that Alexa still works with touch disabled (as long as you disable touch while the mic is still on).  Downside is that this workaround disables touch for the entire room - both Eras and the Arc.

sent sonos L3 info about workaround. 

still waiting on a reply…

Facing the same issue here with Google assistant.

I have the same problem, but it only started when I down loaded the Alexa app and activated voice control 

Just got my ARC 2 days ago. I am having the same issue even with the Sonos Voice. Might open a ticket as well to get this sort it out. I can't even disable the Mic it's just keep turning on and off.
