Feature-Policy: speaker-selection

Feature-Policy: speaker-selection

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

When this policy is enabled and the permission is denied:

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

Syntax

<allowlist>

A list of origins for which the feature is allowed. See Feature-Policy.

Default policy

The default allowlist for speaker-selection is 'self'.
