Volume
Supported in:
Control the iPad volume from within the app settings menu.
Default Value: defined by current iPadOS volume
This setting is included for users who might need to adjust the volume without removing the iPad from an enclosure to access the physical volume controls. As Apple does not currently provide any way for this global setting to be adjusted via an app's .plist settings, this volume control cannot be regulated remotely as part of the remote update of settings.
In Kiosk Pro Enterprise
In the Enterprise version, the slider is replaced with advanced settings to allow separate volume levels for the content and Screensaver, as well as between the iPad speaker and connected headphones.
