Piercing sound from Arc.

. I was watching my TV, and suddenly an intense, extremely loud, piecing sound started being played from my Arc/surrounds. It was so loud that my ears are still ringing 15 min later. The only way I can describe it, is that it sounded like a commercial alarm system siren. I turned off my TV - nothing, unplugged the Arc Ethernet - nothing. Tried to lower the volume - no good. Finally had to pull the main power cord off the Arc to stop it. 
 

I plugged everything back in and it is working fine so far. 
 

This is very concerning. Not just the potential hearing damage, but damage to the speakers from blaring this noise so loudly. 
 

Anyone else experience this?

    This happened to me three times today while trying (without success) to connect my new arc and gen3 sub.  It was so sudden and so loud that I believe there may be permanent hearing damage.  Like others, I tried volume control first then had to scramble to unplug the unit with my head right next to the device.  I have had Sonos products for years and really like the sound quality, but this has certainly given me cause for concern.

      Never had this issue with either Arc I own. As suggested in the post immediately before yours,I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it.

      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 phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.

      Jyst to add, you can contact Sonos Support via this LINK during their usual opening hours to discuss the matter with them.
