That does seem counterintuitive. I’ve got two suggestions, then I’m at a loss, and it could be an issue with Sonos itself.
I tested this on a a PLAY:1 and it does not exhibit this behavior, so it makes me wonder if there’s a slight issue with the Sonos One. I’d try first unplugging the speaker from power, then waiting a minute, and plugging it back in. Essentially forcing a reboot of the speaker.
The other thing I’d try is a toggle of the setting for the LEDs. Turn it back on, then back off.
But, it might help Sonos if you were to submit a diagnostic, too. There may be information in there that would help them track down the issue….or, their may not, unfortunately, as LED status isn’t something I would have thought to include, but who knows, and it certainly is only a moment to do so.
Does the sleep timer end with zero volume? Because green light on a Sonos signifies mute/zero volume.
Mine exhibit this, I use a sticker called LightDims which makes it acceptable.
The sleep timer does indeed reduce the volume but it set the volume back to the volume prior to the sleep command, no green light.
The mute LED does light briefly when the timer expires, presumably because the volume is faded out.
Thanks to all for your replies! It’s good to know that my One is not the only One functioning this way.
Placing something to cover the LED seems like a good first step and I’ll try that and maybe also send an Q to the support.
Cheers!
I’ve got several of their products in a drawer that I find occasionally. More often, I tend to use electrical tape, cut into small pieces. That’s stored in the tools area, and easier to find. ;)
