Examples

If a new {{domxref("AudioContext")}} is created with a sinkId value of { type: 'none' }, calling {{domxref("AudioContext.sinkId")}} later in the code will return a AudioSinkInfo object containing type: 'none'. This is currently the only value available.

audioCtx = new window.AudioContext({
  sinkId: { type: "none" },
});

// ...

audioCtx.sinkId;
