使用XAudio2播放超过400k的wav文件时崩溃

我正在尝试在SlimDX应用程序中设置基本声音,并正在尝试播放音乐。

我注意到我的当前配置会导致应用在文件大小超过400k左右时崩溃。我已经尝试了一些实验来确定问题,但我是Xaudio2的新手,所以有点迷失。

这是我目前播放声音的方法:

public void PlayPCM(XAudio2 device, string fileName)
{
var fileStream = System.IO.File.OpenRead(fileName);
WaveStream stream = new WaveStream(fileStream);
fileStream.Close(); // Close the file stream

AudioBuffer buffer = new AudioBuffer(); 
buffer.AudioData = stream;  // Set data of object to the stream we created from a file
buffer.AudioBytes = (int)stream.Length; // Set the length based on that same file. AudioBytes is an INT.
buffer.Flags = BufferFlags.EndOfStream;

SourceVoice sourceVoice = new SourceVoice(device, stream.Format);
sourceVoice.SubmitSourceBuffer(buffer);
sourceVoice.Start();
}

XAudio2和MasteringVoice对象的设置如下(非常基本):

soundDevice = new XAudio2();
masteringVoice = new MasteringVoice(soundDevice);

我想也许这是一个缓冲区问题,但是因为这是从流(它本身是基于文件)派生的,所以缓冲区的大小肯定会正确吗?

我正在寻找的是一种播放全高品质MP3的机制,因此400k的限制并不实用。

崩溃本身似乎与XAudio2一起,Windows报告:
