Permissions-Policy: speaker-selection directive

{{SeeCompatTable}}

The HTTP {{HTTPHeader("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:

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