I was at the changing of the guard at the Tomb of The Unknown Soldier, Arlington National Cemetery, Washington, D.C. This is a very solemn and silent ceremony, so I set my Sony A6600 camera on silent shooting.
I seldom, if ever, shoot video with this camera but, I wanted to capture a video snippet of the trumpeter playing taps. Not being used to shooting video, I was chagrined when the camera beeped at the start and stop of the video recording! The beep really isn't very loud but, it sounded like a fire alarm at the changing of the guard.
I learned that I needed to stop the camera from making any sounds besides just having it on silent shooting. It seems to me that the selection of silent shooting should cancel any camera sounds. Doesn't that seem reasonable?
I added muting of camera sounds and silent shooting to "My Menu". IMO, the "My Menu" is the most handy part of the Sony menu system.
