Help me! Problem with sound

[Shamaz.mazum]

I can`t play sounds in Crystal Space using CEL. First I attach all needed plugins.
Second I load my sound wrapper.

CsRef<iLoader> loader;
CsRef<iSndSysRenderer> sndrdr;
CsRef<iSndSysManager> sndmgr;
CsRef<iCelPlLayer> pl;
CsRef <MyBehaviourLayer> bl;
....
loader->LoadSoundWrapper ("background", "/mydata/music/tarck02.ogg");

Third, I create music playing entity:

pl->CreateEntity ("music_player", bl, "item", "pcsound.source", CEL_PROPCLASS_END);
csRef<iPcSoundSource> bgsound_source = CEL_QUERY_PROPCLASS_ENT (pl->FindEntity ("music_player"), iPcSoundSource);

Fourth, play sound

bgsound_source->SetSoundName ("background");
bgsound_source->GetSoundSource()->SetVolume (1.0f);
bgsound_source->GetSoundSource()->GetStream()->SetLoopState (
                CS_SNDSYS_STREAM_LOOP);
bgsound_source->GetSoundSource()->GetStream()->Unpause();

On string "bgsound_source->GetSoundSource()->SetVolume (1.0f);" my game crashes.

I can play sounds with iSysSndRenderer and iSysSndManager:
csRef<iSndSysStream> stream = sndrdr->CreateStream (
      sndmgr->FindSoundByName ("background")->GetData(), CS_SND3D_DISABLE);
csRef<iSndSysSource> source = sndrdr->CreateSource (stream);
source->SetVolume(1.0f);
stream->Unpause();
All works perfect, but I want play sounds using CEL. What I am doing wrong? Please help me to learn how to create playable sound source using sound wrappers and CEL.

Hello,

  it would be nice if you could provide a buildable/runnable example for the problem,
it could speed up the testing. I'm willing to investigate, but I don't have much time at the
moment and will be away next week (using CS/scripts/jamtemplate/createproject.sh to create
a test case easy to build/run on any platform is a good idea).
Someone else might do it before I do, tho...

Unfortunately, I can`t provide buildable variant because it have size of 180MB and because of strange promblem with forum: I can`t upload anything. I think all I can to do, it is give you some pieces of code if you need.

NB:Last post I forgot say you that I set up sound listener properly: it always follows the player mesh.

I'm not sure, but i think the "iPcSoundSource" property is not yet implemented in current CEL version because the "SetSoundName" method implementation is:

Code:

void celPcSoundSource::SetSoundName (const char* name)
{
  soundname = name;
  soundwrap = 0;
  source = 0;
  source3d = 0;
  stream = 0;
}

I imagine it shoulds be something like this:

Code:

void celPcSoundSource::SetSoundName (const char* name)
{
  soundname = name;
  soundwrap = 0;
  source = 0;
  source3d = 0;
  stream = 0;

  GetSoundWrap();

  if (!GetSource())
  {
    // @@@ Report error?
    printf ("Can't set sound '%s'!\n", (const char*)name);
    fflush (stdout);
  }
}

Thanks, Zuck.

Please, give me a feedback if it works...
