Hi Mike,

I appreciate the response, that's actually not a bad idea and pretty easy to implement. That said, it doesn't seem to be the issue. I changed over the code to use a single device and the same issue is present.

I should mention that I'm not locked to SlimDX... if you (or anybody else) has thoughts on alternatives I'm all ears (eyes?). My engine is structured in such a way that I can replace the component that does the actual sound playing fairly easily so I should be able to use any old sound provider. My only requirements are that it can play in a thread and that I can play/stop it (pause is a nice to have but not required). Currently SlimDX using XAudio2 grants me this functionality. I did try SlimDX with DirectSound, but was getting an odd artifact at the end of playback... just a little click sound, so I went with XAudio2.

Here's the updated class for you or any others looking at this thread.

public class SoundPlayer
{
	private SourceVoice m_sourceVoice = null;

	public SoundPlayer()
	{
	}

	public void Load(XAudio2 device, string fileName)
	{
		WaveStream waveStream = new WaveStream(fileName);

		AudioBuffer buffer = new AudioBuffer();
		buffer.AudioData = waveStream;
		buffer.AudioBytes = (int)waveStream.Length;
		buffer.Flags = BufferFlags.EndOfStream;

		m_sourceVoice = new SourceVoice(device, waveStream.Format);
		m_sourceVoice.SubmitSourceBuffer(buffer);
	}

	public void Load2(XAudio2 device, string fileName)
	{
		byte[] fileData = File.ReadAllBytes(fileName);
		MemoryStream ms = new MemoryStream(fileData);

		WaveStream waveStream = new WaveStream(ms);

		AudioBuffer buffer = new AudioBuffer();
		buffer.AudioData = waveStream;
		buffer.AudioBytes = (int)waveStream.Length;
		buffer.Flags = BufferFlags.EndOfStream;

		m_sourceVoice = new SourceVoice(device, waveStream.Format);
		m_sourceVoice.SubmitSourceBuffer(buffer);
	}

	public void Play()
	{
		Thread t = new Thread(PlayMethod);
		t.Start();
	}

	private void PlayMethod()
	{
		m_sourceVoice.Start();
		while (m_sourceVoice.State.BuffersQueued > 0)
		{
			Thread.Sleep(10);
		}

		m_sourceVoice.Dispose();
	}
}

Then using it...

public class TestHarness
{
	private XAudio2 m_device = new XAudio2();

	public TestHarness()
	{
		MasteringVoice masteringVoice = new MasteringVoice(m_device);
	}

	public void RunTest()
	{
		SoundPlayer p1 = new SoundPlayer();
		SoundPlayer p2 = new SoundPlayer();
		SoundPlayer p3 = new SoundPlayer();

		p1.Load2(m_device, @"..\..\klaxon2.wav");
		p2.Load2(m_device, @"..\..\klaxon2.wav");
		p3.Load2(m_device, @"..\..\warn2.wav");

		p1.Play();
		//p2.Play();
		//p3.Play();
	}
}
