    copied!<p>im trying to play a looping sound in openGL/SDL with openAL but when im calling it its just looping infinitely and its stuck at the start ive got no idea how to fix this so i came here hoping some1 knows heres my code of how im calling openAL</p> <pre><code>SDL_Thread * AudioBG; bool Init(void) { m_Music-&gt;LoadFile("Sonido/BGSP.wav",true); } int MusicThread(void *arg)//Creating the Thread { arg+=0; for(;;) { m_Music-&gt;PlaySound(); } return 0; } void Draw()//this is my cycle of the game { gui-&gt;Draw(x,y,z); AudioBG = SDL_CreateThread(Music,NULL); } </code></pre> <p>this is my class Sound.cpp</p> <pre><code>Sound::Sound() { Device = alcOpenDevice((ALCchar*)"DirectSound3D"); Context = alcCreateContext(Device,NULL); alcMakeContextCurrent(Context); alGetError(); } Sound::~Sound() { Context = alcGetCurrentContext(); Device = alcGetContextsDevice(Context); alcMakeContextCurrent(NULL); alcDestroyContext(Context); alcCloseDevice(Device); } void Sound::LoadFile(char archivo[40],bool looping) { ALboolean loop; loop = looping; alutLoadWAVFile(archivo,&amp;alFormatBuffer, (void **)&amp;alBuffer, (ALsizei *)&amp;alBufferLen, &amp;alFreqBuffer,&amp;loop); alGenSources(1,&amp;this-&gt;alSource); alGenBuffers(1,&amp;alSampleSet); alBufferData(alSampleSet,alFormatBuffer,alBuffer,alBufferLen,alFreqBuffer); alSourcei(this-&gt;alSource,AL_BUFFER,alSampleSet); alutUnloadWAV(alFormatBuffer,alBuffer,alBufferLen,alFreqBuffer); alSourcef(this-&gt;alSource,AL_PITCH,1.0f); alSourcef(this-&gt;alSource,AL_GAIN,1.0f); if(looping) alSourcei(this-&gt;alSource,AL_LOOPING,AL_TRUE); else alSourcei(this-&gt;alSource,AL_LOOPING,AL_FALSE); } void Sound::Direction(float x,float y,float z,float vx,float vy,float vz) { alSource3f(this-&gt;alSource,AL_POSITION,x,y,z); alSource3f(this-&gt;alSource,AL_VELOCITY,vx,vy,vz); } void Sound::RelativeSound() { alSourcei(this-&gt;alSource,AL_SOURCE_RELATIVE,AL_TRUE); } void Sound::PlaySound() { alSourcePlay(this-&gt;alSource); } </code></pre> <p>im really lost... if i call the function LoadFile and initialize the song out of the game loop and without a thread it plays well but inside the loop and with or without the thread im getting the error i tried to describe :S</p>
