Hi, I have a Sonos Play5 Gen1 - when plugged up to power there is a buzzing or squealing noise coming from the unit.
It has been doing it for a few years, but since I first heard it I keep it powered off and it’s not been used. Its twin sister misses it and wants it back and to be paired up again.
what is causing this?
is there a genuine fix without cost or replacement?
Thanks in advance.
