这是MAC OSX 10.8.5的结果
Google Chrome版本39.0.2171.27 beta(64位)
和版本40.0.2192.0金丝雀(64位).

Safari不允许我处理超过2个频道
FireFox使用audioContext.destination.maxChannelCount找到我的12个频道,但是继续将我的声音路由到频道1& 2,无论我是否尝试通过gain.connect(channelMerger,i)将振荡器连接到较高的数字.

有没有人遇到过类似的事情？有解决办法吗？

这是代码：

var AudioContext = window.AudioContext || window.webkitAudioContext;
var audioContext = new AudioContext();
var maxChannelCount = audioContext.destination.maxChannelCount;

// if set to max 8 it works fine in Chrome,but this line
// breaks the audio if the sound card has got more than 8 channels
audioContext.destination.channelCount = maxChannelCount; 
audioContext.destination.channelCountMode = "explicit";
audioContext.destination.channelInterpretation = "discrete";

var channelMerger = audioContext.createChannelMerger(maxChannelCount);
channelMerger.channelCount = 1;
channelMerger.channelCountMode = "explicit";
channelMerger.channelInterpretation = "discrete";
channelMerger.connect(audioContext.destination);

for(var i = 0; i < maxChannelCount; i++){
    var oscillator = audioContext.createOscillator();
    oscillator.connect(channelMerger,i);
    oscillator.start(0);
}
