Stream sound

There is a problem with streaming sound (in a separate thread)? If the source is starved of audio data then it stops playing, and then it needs to be restarted.

Can you please be more specific or simply send me a template project by email that reproduce the bug.

Tks!

I want to play a background music in the game which is updated in a separate thread. So I created a thread like this:

_SIO2thread = sio2ThreadInit();
sio2ThreadCreate(_SIO2thread, MusicUpdateThread, ( void * )g_pGame, SIO2_THREAD_PRIORITY_NORMAL);
sio2ThreadPlay(_SIO2thread);

Here's the thread function:

void MusicUpdateThread( void *_ptr )
{
CGame* pGame = (CGame*)_ptr;
SIO2sound* pSound = NULL;

pSound = pGame->GetGameMusic();
if (pSound) sio2SoundUpdateStream(pSound);
}

And if I add this to the "void sio2SoundUpdateStream( SIO2sound *_SIO2sound )" function after the "if( !q )":

else
{
int iState;

// Check the status of the Source. If it is not playing, then playback was completed,
// or the Source was starved of audio data, and needs to be restarted.
alGetSourcei(_SIO2sound->sid, AL_SOURCE_STATE, &iState);
if (iState != AL_PLAYING && iState != AL_PAUSED)
{
// source was starved of audio data
sio2SoundPlay( _SIO2sound );
}
}

the state of the source will be AL_STOPPED. But now the last buffer is played again, before it continues.

Hi,
I have simple problem when trying play backgrownd music. I use double buffering for sound, but hear only one....

Code:


void LoadSound (void)
{
   {
      SIO2stream *streamSound = NULL;
      streamSound = sio2StreamOpen("mozart_sym40_1.ogg", 1);
      if (streamSound)
      {
         SIO2soundbuffer *soundBuffer = sio2SoundBufferInit("music");
         sio2SoundBufferLoad(soundBuffer, streamSound);
         sio2SoundBufferGenId(soundBuffer, 1);
         
         music = sio2SoundInit("music");
         sio2SoundGenId(music, soundBuffer, SIO2_SOUND_STREAM|SIO2_SOUND_LOOP);
         sio2SoundBufferFree(soundBuffer);
      }
      sio2StreamClose(streamSound);
}
void templateRender( void )
{
...
static bool b = false;
   if (!b)
   {
      sio2SoundPlay(music);
      b = true;
   }
   sio2SoundUpdateState(music);
   if (music->state != SIO2_SOUND_PLAY)
   {
      sio2SoundUpdateStream(music);
   }
}


Can you help me?

sio2ResourceRender( level,
sio2->_SIO2window,
sio2->_SIO2camera,
SIO2_RENDER_SOLID_OBJECT | SIO2_RENDER_ALPHA_OBJECT | SIO2_UPDATE_SOUND_STREAM );

I change my LoadSound function and all working!
Thanks

I'm using exactly the code you have above, but my sound just plays for a bit and then loops.
The same happens when I load the sound through Blender like on tutorial 15.

Can you or someone tell me what's happening please?

Thanks
