Intermittent chirping/squeeking sound on all my Sonos speaker (at the same time) (S1 System)

Here’s a weird thing I appeared to be getting an inductive squeal feed back from one PowerPoint to which the speaker squealing was plugged into. After swapping power points the noise disappeared. I now need to investigate the wiring. Maybe the power point is being effected by a light rectifier or something similar that is causing a transient to be coupled onto the wiring?

I’m getting a loud “chirp” in my 5s when steaming through my ROKU Ultra. The kind of chirp that can make one jump and go “what the hell was that?” I can understand an occasional audio drop streaming via WiFi (there’s another chirp but not nearly as loud.) but, why now? This is something that’s only manifested in the past two+ weeks. Is Tech Support looking into a software update? 

Have you submitted a system diagnostic within 10 minutes of getting one of these ‘chirps’, and called Sonos Support to discuss it?

I don’t think it’s a common issue, it is entirely possible they’re coming from somewhere other than the connection of your Sonos to the TV. Likely the data in the diagnostic might help figure it out. 

Thanks, Bruce. No, I haven’t submitted a diagnostic. Good to know that it should be run and submitted within 10 of an incident. I’ll do that the next time the speaker chirps at me.

If you’d be so kind as to come back and post what you find out, I’d certainly be fascinated.

If we watch something on the tube tonight I’ll be ready. Another thought: It could be due to a power surge or interruption due to an extremely brief outage. We’ve had heavy snow and, we also had a surge this morning that necessitated restarting our modem/router due to a lost internet connection. Regardless, I’ll attempt a diagnostic right after the next chirp. Thanks again, Bruce.

I just got off the phone with Sonos Support regarding my audio drop offs and intermittent chirping. After the Diagnostic report was reviewed, we removed my Sonos 5s as surrounds, reset the one that I heard the chirp and drop offs coming from and then, re-added the 5s back into the system as surrounds.

The agent suggested it could be a number of things. One being the router channel. Sonos uses router channel #6 and there are also channels 1 and 11. One has to contact their provider to find out how to change those if one believes the traffic on channel 6 might be causing the audio drop offs.

During my wait time, the recording informed me that one could search “Audio Skips” on the Sonos website and be directed towards a page that lists things one can do to try to alleviate the drop offs in the audio signal. These range from checking HDMI and optical cable connections (I’ve had optical cables go bad) and resetting either the TV, Roku box...etc. One other suggestion is to check your “pass through” settings on your tube; I believe that is specific to Dolby. These suggestions seem to make sense considering the audio has to travel through those units before they come out of the speakers.

All in all, I think it’s a combination of issues colliding to form a minor annoyance. Power surges, data rate fluctuations, component hiccups...etc. No concrete answer on the “chirps” but, I’ll keep monitoring the issue and see if I need to go through the aforementioned steps listed above.

I hope this helps a bit with anyone else’s issues on this matter.
