What the problem?

Hello!

Here is detailed description the difference programming sound using OpenAL in Linux OS (Windows is OK)

We have two applications, that using Open AL and OpenGL… we are using less than 120 sound sources

We have different computers with different sound cards (Realtek and Creative X-Fi)

Linux: Ubuntu 10.04 amd64, Open AL ver. 1.12.854

When the load of processor increasing up to more than 70 percent, we got a hard stammering of sound and experience rough fall of FPS. We can see that only if the position of recipient is always the same, never had been changed. If we permanently changing the position of recipient, we don`t get that bug.

I wrote the code to solve that issue in Linux OS

#ifdef WIN32

if ((oldX!=posx)||(oldY!=posy)||(oldZ!=posz))

{

ALfloat ListenerPos[] = { posx, posy, posz };

alListenerfv(AL_POSITION, ListenerPos);

CheckALError();

}

#else //this FIXed BUG in linux

{

ALfloat ListenerPos[] = { posx + (rand() % 2 + 1), posy+ (rand() % 2 + 1), posz+ (rand() % 2 + 1) };

alListenerfv(AL_POSITION, ListenerPos);

CheckALError();

}

#endif

What the problem? What`s the way out?
