Created Issue: AccessViolationException when disposing WaveOut in a 64-bit application [16369]

I'm currently migrating my application to 64-bit and whenever I'm trying to dispose the WaveOut class, I'm getting an "AccessVoilationException" with the message "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."

Stacktrace:

at NAudio.Wave.WaveInterop.waveOutClose(IntPtr hWaveOut)
at NAudio.Wave.WaveOut.Dispose(Boolean disposing)
at NAudio.Wave.WaveOut.Dispose()

I've tested this with version 1.5 and 1.6 of NAudio, it only happens when I compile my application for 64-bit, 32-bit works fine.

Small codepiece where it happens:

if (wavePlayer != null)
{
this.wavePlayer.Stop();
this.wavePlayer.Dispose(); //AccessViolationException
}
