Hi, I posted this a year ago, and was asked to submit diagnostics:
“I have 4 play:1 speakers set up as two stereo pairs in different rooms. One of the units has started putting out a 1-2 second buzzing or whirring noise while not in use. I am having a quiet afternoon watching cricket and football and have heard the noise 4 times. Unplugging and restarting makes no difference.”
However, the noise went away so I did not submit. Today I have been sat next to the speaker and heard it maybe a dozen times while no part of my sonos system is actually in use. It is the LH speaker of a stereo pair connected to a Beam. Can I submit a diagnostic?
thanks, Alan
