Hi @Jos07.
Welcome to the Sonos community and thanks for reaching out to us. I would like to share some information to help out.
From this point, I would recommend calling our technical support team for more in-depth troubleshooting steps or possible product replacement. It is best to contact our technical support team so they can dig deeper and asses what would be the better step to take and what is causing the issue as it may be an internal hardware fault.
I hope this helps.
Please let me know how it goes and keep me posted.
Thanks,
