I've already followed the steps here (although modified a bit, since I think that example wasn't using Android 11) to disable screenshot sound notifications:
But the setting seemed to have no effect.
There is still a sound whenever I take a screenshot by holding the power button and the Volume Down button.
How can I disable the sound?
This is not possible unless 1. you have root access(delete the sound file) or 2. Use a 3rd party trusted screenshot app or 3. Disable system sound(yeah it will disable notifications sounds and all too) I'd recommend you to use a 3rd party app(you can use power and volume button to take screenshots by the app by over-riding system's screenshot system) You can try Screenshot Assistant from fdroid or Screenshot or Screenshot sharer(super helpful if you don't use google assistant much) from fdroid. fyi fdroid is super trusted.
" The Silence option refers to the notification you see with the preview of the screenshot. Try editing some other options in there (try making it alerting and then enable 'Pop on screen'). You will see what I mean. And yes, you're correct in saying that setting it as Silence or Alerting doesn't actually make a difference to the sound - it doesn't occur anyway.
There is no user facing control to silence the sound emitted while the screenshot is being taken."
