Hi, I have some problems with Buffer3D. A time ago I have used directsound with no problem then I become cruious about 3d support(and where the problems begin). But then I encounter with an exception, I look around but can t see the problem. here is the portion code portion responsible from this problem :)


Buffer m_soundBuffer;
Buffer3D m_3dSoundBuffer;
..
..

BufferDescription desc = new BufferDescription();
desc.Control3D   = true;
desc.GlobalFocus = true;

// Below line is the cause of exception which says "Value does not fall within the expected range"					
m_soundBuffer = new Buffer(i_name, desc, i_sound.Device);
m_3dSoundBuffer	= new Buffer3D(m_soundBuffer);
m_3dSoundBuffer.Mode = Mode3D.Normal;

I am using vs.net2003, dx9c and my sound card is SBLive 5.1. Thanks in advance...

ive wrapped up the creation code so all you haev to do is call the interface.

h

class ADX_API Sound3D {private:	LPDIRECTSOUND3DBUFFER g_pDS3DBuffer;	DS3DBUFFER g_dsBufferParams;public:	Sound3D();		~Sound3D();	bool create(LPDIRECTSOUNDBUFFER sb);	LPDIRECTSOUND3DBUFFER getSound3DBuffer(){return g_pDS3DBuffer;}};class ADX_API Sound3DListener {private:	LPDIRECTSOUND3DLISTENER g_pDSListener;	DS3DLISTENER g_dsListenerParams;   public:	Sound3DListener();	~Sound3DListener();	bool create(LPDIRECTSOUND8 ds);	LPDIRECTSOUND3DLISTENER getSound3DListener(){return g_pDSListener;}};

cpp

bool Sound3DListener::create(LPDIRECTSOUND8 ds){	LPDIRECTSOUNDBUFFER pDSBPrimary = NULL;    DSBUFFERDESC        dsbdesc;    ZeroMemory( &dsbdesc, sizeof(DSBUFFERDESC) );    dsbdesc.dwSize = sizeof(DSBUFFERDESC);    dsbdesc.dwFlags = DSBCAPS_CTRL3D | DSBCAPS_PRIMARYBUFFER;	if( FAILED( ds ->CreateSoundBuffer( &dsbdesc, &pDSBPrimary, NULL ) ) )	{		return false;	}  	if( FAILED(  pDSBPrimary->QueryInterface( IID_IDirectSound3DListener,                                                   (VOID**)&g_pDSListener ) ) )    {        SAFE_RELEASE( pDSBPrimary );		return false;	}		SAFE_RELEASE( pDSBPrimary );	if(FAILED(g_dsListenerParams.dwSize = sizeof(DS3DLISTENER)))		return false;	if(FAILED(g_pDSListener->GetAllParameters( &g_dsListenerParams )))		return false;	return true;}Sound3DListener::Sound3DListener(){	g_pDSListener = NULL;}Sound3DListener::~Sound3DListener(){	if(g_pDSListener)	{		g_pDSListener->Release();		g_pDSListener = NULL;	}}Sound3D::Sound3D(){	g_pDS3DBuffer=NULL; }Sound3D::~Sound3D(){	if(g_pDS3DBuffer) { 		g_pDS3DBuffer->Release(); 		g_pDS3DBuffer=NULL; 	}}bool Sound3D::create(LPDIRECTSOUNDBUFFER sb){	if(FAILED(sb->QueryInterface(IID_IDirectSound3DBuffer, 												(VOID**)&g_pDS3DBuffer )))		return false;			g_dsBufferParams.dwSize = sizeof(DS3DBUFFER);	if(FAILED(g_pDS3DBuffer->GetAllParameters( &g_dsBufferParams )))		return false;	g_dsBufferParams.dwMode = DS3DMODE_HEADRELATIVE;	if(FAILED(g_pDS3DBuffer->SetAllParameters( &g_dsBufferParams, DS3D_IMMEDIATE )))		return false;			DSBCAPS dsbcaps;	ZeroMemory( &dsbcaps, sizeof(DSBCAPS) );	dsbcaps.dwSize = sizeof(DSBCAPS);		if(FAILED(sb->GetCaps( &dsbcaps )))		return false;		return true;}
