Audio + Video API volume control

[shalanah]

Description

All browsers should allow for volume control from 0.0-1.0 for Audio + Video APIs.

iOS/iPadOS WebKit does not allow for volume control (it is "read-only").

Use cases:

• Sound effects (varying % or just want at less than 100% without having to re-export sound)
• Background sounds that you want at less than 100% for ambiance
• Volume controls around video elements

Special care needs to be added for iOS/iPadOS only to turn volume off via mute since setting volume to zero doesn't work.

The explanation that has been given, is that Apple thinks the user should always be in control of volume via physical buttons for iPhones and iPads. Apple only upholds this value for the web and does not include this restriction on its apps including Apple Music.
