Hello,
I had purchased a refurbished Era 300 from Sonos on 06/07/24. I have installed it with the Arc, Subwoofer g3, and another Era 300 (replacing my Ones) as surrounds. For some reason the speaker keeps flashing white and red. I have searched on numerous web forums and looked on YouTube but cannot find an answer to why this is happening. I have tried a hard reset on the speaker, taking the speaker off my system and adding on to it again several times, rebooting my WiFi but the same issue persists. Last night I played again with the system and found out the problem stopped when I turned off the microphone on the speaker. I noticed on the app the microphone was flashing on and off corresponding with the flashing lights on the speaker. I am getting sound from the speaker as it flashes. I am unsure if this is a hardware issue. I have no issues with my other Era 300.
Please advise.
