The HTTP Permissions-Policy header speaker-selection directive controls whether the current document is allowed to enumerate and select audio output devices (speakers, headphones, and so on).

Specifically, where a defined policy blocks use of this feature:

• MediaDevices.enumerateDevices() won't return devices of type audio output.
• MediaDevices.selectAudioOutput() won't display the popup for selecting an audio output, and the returned Promise will reject with a DOMException of type NotAllowedError.
• HTMLMediaElement.setSinkId() and AudioContext.setSinkId() will throw a NotAllowedError if called for an audio output.

Syntax
