This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The gain property of the GainNode interface is an a-rate AudioParam representing the amount of gain to apply.
Value

Note:
Though the AudioParam returned is read-only, the value it represents is not.

See BaseAudioContext.createGain() for example code showing how to use an AudioContext to create a GainNode, which is then used to mute and unmute the audio by changing the gain property value.
