There are several posts on here about exactly the same thing - all misteriously ticked as ‘answered’ by the admins, yet like the others who posted, I have tried absolutely every recommendation suggested and nothing works.
The only sign of life is an orange light when plugged in to charge via USB-C. and yes, I have left it over an hour charging, and yes, with a 15w charger, and yes, i have pressed the power button for 5 seconds, 10 seconds, 30 seconds and yes, i have combined that with pressing the play/pause button. But like others, I still have a speaker that is only 2 years old which is now a defective brick.
I bought the speaker directly from Sonos so I am not holding my hopes up at getting anything other than a 30% off voucher, which quite frankly doesn’t cut it for a problem that seems to be widespread.
Suggestions welcome!
