Alexa 'Scratch' Sound

I have a new (~3 weeks) Sonos Era 100 that has developed a digital ‘scratch’ sound when waking up the voice assistant. Whenever I say “Alexa…” I’ll get the chime and what sounds like a short scratch/static sound. The rest of audio playback is fine, music is unaffected, and I’ve not heard this same sound aside from using the wake word.

Restarting the speaker didn’t do anything and I’m not sure if this is something I should initiate a return for, or if its a known issue with a fix.

Ideas are welcome.

I went to the Sonos Arc in the Alexa app. Under “Sound”, I disabled the “Start of Request” sound. The “scratch sound” is gone, but the Wake Chime is still there.

So, it’s still not working quite right, but I like the Wake Chime, so this is good enough for me!

Did you try the other suggested solutions?

Yes, the toggling. ANd togglign in the Amazon app did resolve the issue, as i stated above.

Im not going through 25 speakers and removing and re-adding Alexa. Either Amazon and/or Sonos need to fix. What we all did are bandaids.

Same here. Removed Alexa and re added it. Took 2 minutes.

In case it helps anyone else, had this exact issue on my Sonos One and removing and then re-adding alexa worked to remove the digital scratch sound.

Identical problem, removing & re-adding alexa fixed it.

For the 2 minutes / speaker it takes, just do it.

This started happening on my Arc yesterday. Removed & reinstalled Alexa and the static sound disappeared.

Easy fix - thanks!

Same issue here on three separate Alexa enabled Sonos speakers (2 x Play One, and 1 x Arc). Do I need to disable and tenable voice individually on each speaker or do I need to do all at once?

I'm not sure if this will help anyone else, but I wanted to share a quick update regarding the audio issues. I just updated the Sonos app and reinstalled Alexa, and that awful noise is finally gone! 😀
Hopefully, this might be a solution if anyone else is experiencing the same problem.

Happened on my Move. Fixed by going in to the Sonos app, finding my move, then removing then re-adding alexa.

I fixed this by turning on wake sound in the Sonos app and turned off wake sound in the alexa app

The scratch sound after you hear the wake up chime (having said ‘alexa’) can affect any sonos install in any room. Delete the voice assistant and re-adding it will definitely the problem. It’s happened to my system twice - kitchen is two x era100, lounge is 2 x era 100 + beam + mini sub. The last occurrence ONLY affected the lounge system and not the kitchen system. Will talk to Sonos tomorrow - the chat bot is pretty quick and if it happens again, I’ll submit diagnostics. This is definitely not a wifi, reset or set up problem and needs fixing based on the content of this thread and the random manner in which it presents itself

I had the same issue on my Arc ultra so I removed Alexa from Sonos app and reconfigured it. Also while reconfiguring I changed the language from English (India) to English (United States) that effectively solved the issue.
