Author Topic: Delays / program locks after playing sounds (Read 28855 times)

I recently added some sounds to my current project and noticed that there were some very brief delays in my display and then several seconds later a much longer pause - basically the program locks up for a few seconds. It was very noticeable as it's a scrolling 3D view drawn with OpenGL. I'm tried WAV and OGG files and the result is the same. The sounds themselves seem to play fine.

I've tried adding a simple sound to play in the SFML OpenGL example of the white cube and got the same results. I added these lines just before the start game loop:

sf::SoundBuffer doorBuffer;
sf::Sound doorSound;
doorBuffer.LoadFromFile("datas/audio/door.wav");
doorSound.SetBuffer(doorBuffer);
doorSound.Play();

I'm using Windows XP, the latest SVN and Visual Studio. I haven't had the chance to test this on another PC yet.

Thanks.

That's weird. I'll check this as soon as possible, thanks for the feedback.

I've tried your code in the OpenGL sample, and couldn't reproduce the bug.

Can you try again with the latest SVN, and footsteps.wav from the samples data ?

I've updated to the latest SVN and tried the footsteps.wav file and I get the same result. As far as I can see I'm using the most recent verions of everything.

I've tried a few different sound files and it appears that the freeze appears about 20 seconds after the sound finishes playing. I also tried this on another PC and had the same result.

Which version of SFML are you using ? Debug / release ? Static / dynamic ?
Which version of Visual Studio ?

I still can't reproduce the bug, although I'm using the exact same configuration and code as you.

I'm using the latest SVN. I had previously used 1.2 and experienced the same problem. I'm using debug mode with I think dynamic libraries (I need to include the SFML DLLs in my project folder in order to run my executable).

The following libraries are in the project settings:

sfml-system-d.lib sfml-window-d.lib sfml-graphics-d.lib sfml-audio-d.lib opengl32.lib glu32.lib

I'll try release / static.

Thanks.

... and Visual Studio 2005 Professional with C++.

Ok, let me know if there's a difference with static libraries.

After more tests with different PCs and the different libraries it seems to have been some strange combination problem with my Visual Studio setup / libraries on my main PC rather than SFML. Sorry. Thanks for your looking into this.

Ok, that's a good news
