Hi,
The .NET 2.0 SoundPlayer class internally uses winmm API PlaySound
(
http://msdn2.microsoft.com/en-us/library/ms712879.aspx) to play the wave
file and this API cannot play multiple wave files simultaneously in a
process.
To workaround this, you will either use DirectX or use Windows Media Player
to play the wave files:
1) Reference c:\windows\system32\wmp.dll
2) Use following code:
WMPLib.WindowsMediaPlayer wp = new WMPLib.WindowsMediaPlayer();
wp.URL = @"c:\1.wav";
WMPLib.WindowsMediaPlayer wp2 = new WMPLib.WindowsMediaPlayer();
wp2.URL = @"c:\2.wav";
This will play the two wave files simultaneously.
Here's some tutorials on using Managed DirectX to play sound:

Hope this helps.
