Macbook M1 MAX late 2021 no chime sound on startup
I'm using now for a month my new Macbook M1 Max 64Gb Ram 1Tb a week ago the chime sound on startup, mysteriously stopped. I did search for some possible causes, looked into sound preferences and did a nvram reset, unfortunately chime still missing. Any help will be appreciated.
Thanks
MacBook Pro 16″, macOS 12.0
