setSinkId 更改多个音频输出 [英] setSinkId change muliple audio ouputs

问题描述

问题来了，

首先，我在 select 元素中列举了所有可用的设备:

First I enumerate all the devices that I have available with in select elements:

navigator.mediaDevices.enumerateDevices()

当我更改一个输出时，它会在我选择的设备中发出声音.

When I change one output, it sounds in the device that I choose.

HTMLMediaElement.setSinkId(deviceId)

如果我播放另一个音频并更改设备输出 (setSinkId)，它也会将第一个更改为最后一个 deviceId.所以我在同一个设备上有两种声音.

After if I play another audio and change the device output (setSinkId), it changes also the first one to the last deviceId. So I have both sounds in the same device.

我是否需要使用最新的adapter.js 版本才能正确实现该问题?

Do I need to have the last adapter.js version to implement properly that problem?

按照上面的评论，它尝试了网络音频，但没有成功.使用 getUserMedia 一切正常.

Following the above comment, it try the web audio, but not success. With getUserMedia everything is fine.

navigator.getUserMedia( { audio: true, video: false },
    function (mediaStream) {
        // Create an audio context for the audio
        var ac = new (window.AudioContext || window.webKitAudioContext)();
        // Create a clone of the stream, if not the id of all the stream is default
        //var streamClone = stream.clone();
        var ss = ac.createMediaStreamSource(mediaStream);
        // Create a destination
        var sd = ac.createMediaStreamDestination()
        ss.connect(sd);
        element.srcObject = sd.stream;
        // Play the sound
        element.play();
        element.setSinkId(deviceId).then(function() {
            console.log('Set deviceId('+deviceId+') in the selected audio element');
        });
    },
    function (error) {
        console.log(error);
    }
);

但是使用我的远程流，我听不到任何噪音

But using my remote stream, I cannot get any noise

var ac = new (window.AudioContext || window.webKitAudioContext)();
// Create a clone of the stream, if not the id of all the stream is default
var streamClone = stream.clone();
var ss = ac.createMediaStreamSource(stream);
// Create a destination
var sd = ac.createMediaStreamDestination()
ss.connect(sd);
// Element is my HTMLMediaElement
element.srcObject = sd.stream;
// Play the sound
element.play();
element.setSinkId(deviceId).then(function() {
   console.log('Set deviceId('+deviceId+') in the selected audio element');
});

推荐答案

这很可能是由 Chrome 呈现音频的方式引起的.请参阅此处有关还建议使用 webaudio 解决问题的说明.

this is most likely caused by how Chrome renders audio. See here for a description which also suggests using webaudio to workaround the problem.

adapter.js 无法解决这个问题.

adapter.js can not fix this.
