HTMLMediaElement: setSinkId() method

sinkId

The MediaDeviceInfo.deviceId of the audio output device.

A Promise that resolves to undefined.

NotAllowedError DOMException

Returned if a speaker-selection Permissions Policy is used to block use of audio outputs.

NotFoundError DOMException

Returned if the deviceId does not match any audio output device.

AbortError DOMException

Returned if switching the audio output device to the new audio device failed.

Access to the API is subject to the following constraints:

• The method must be called in a secure context.
• Access may be gated by the speaker-selection HTTP Permission Policy.
• User permission is required to access a non-default device. The user grants permission by selecting the device associated with the ID in the prompt displayed by MediaDevices.selectAudioOutput().

This example shows how to select an audio output device from the array returned by MediaDevices.enumerateDevices(), and set it as the sink for audio. Note that the result of enumerateDevices() only includes devices for which user permission is not required or has already been granted.

const devices = await navigator.mediaDevices.enumerateDevices();
const audioDevice = devices.find((device) => device.kind === "audiooutput");
const audio = document.createElement("audio");
await audio.setSinkId(audioDevice.deviceId);
console.log(`Audio is being output on ${audio.sinkId}`);
