Hello there,

I am programming a simple game for Windows Mobile, managed code C# with .NET 
compact framework. In the game, I want to play some sounds (which I've stored 
as sound resources in my project) when some actions occur. I found two ways: 
The Media.Soundplayer .NET class and the PlaySound API method. I tried both 
ways and there is a problem:

The API call to PlaySound just works fine, doesn't have any glitch.
The SoundPlayer.Play method has a serious glitch. The game stucks for about 
a second (or half a second) before the sound begins to play. Is there 
something wrong with the SoundPlayer.Play method, or am I doing something 
wrong?

Hi,

I assume you are using .NETCF v3.5 beta as prior versions don't have the 
System.Media classes. The way this class works is it loads in the file 
internally and plays from the local cache of data. PlaySound simply plays 
directly from the given file path (or memory buffer). You can work around 
this by calling the Load() or LoadAsync() methods elsewhere in your code 
prior to needing the sound. If the load is already done Play should perform 
much better. Currently Play is having to first load the file which explains 
the delay.

Peter

Thanks Peter for your quick response,
& congrats for your MVP

Well, I had tried what you said, in two ways: loading the sound from a file, 
and loading the sound from a MemoryStream. They presented glitches. But in 
the end I found out what the real problem was: Not surprisingly, I was 
running the program always through Visual Studio (which monitors the program 
while debugging and imposes a certain load on it), and that was why the 
SoundPlayer presented glitches. I ran the program by itself and everything 
worked just fine. Thanks for your response.
I should comment that SoundPlayer was a very nice addition in v3.5.
