Hey @sumosucker, welcome back!
It sounds incredibly frustrating to deal with a buzzing Sonos Amp, especially after trying so many solutions.
From looking at your case, I can see that you should have received an offer to replace your defective Sonos Amp. I also noticed that there is another ongoing case, and a colleague should reach out to you soon.
While I can always review ongoing cases, I can only refer you to colleagues from the Support team for issues related to defective units and their replacements.
Hi Sotiris
I was told by the support agent the case was closed and there was no more they could do to help. If you know anyone that can help me please do as it is driving me up the wall! I just want it to work properly!
Thanks, sumo
SONOS does not offer service. In the EU and UK there are some 3rd parties offering SONOS service.
