Unknown popping sound recurring; usually not long after start.
I often get a popping sound from my iMac (using updated Monterey) through the speakers about two seconds after "Chrome" is opened (also there when Incognito mode is opened) . In System Prefs. every item either has all Notifications set to off or the “Play sound for notifications” turned off; its not a startup sound which is also set to Off; I haven’t discerned what if anything it is indicating - so I’d like to know what it indicates and whether it can be turned off? The sound selected for notifications is not a popping sound so it seems it is coming from some other area.
