Simultaneous Sounds

I'm using the .Net 2.0 SoundPlayer class for the sound effects in my app. But it doesn't seem to allow simultaneous sounds... I'm even executing the instantiation and play on a separate thread. But sound two never gets played. Anyone have much experience with this?

Thanks.

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\syst em32\wmp.dll
2) Use following code:

WMPLib.WindowsM ediaPlayer wp = new WMPLib.WindowsM ediaPlayer();
wp.URL = @"c:\1.wav";

WMPLib.WindowsM ediaPlayer wp2 = new WMPLib.WindowsM ediaPlayer();
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.
