在ＢＣＢ中CreateCaptureBuffer的怪病！

[strongsoft]

LPDIRECTSOUNDCAPTURE g_pDSCapture= NULL;
GUID* pDeviceGuid=NULL;
DirectSoundCaptureCreate(pDeviceGuid, &g_pDSCapture,NULL);
WAVEFORMATEX wfx;
ZeroMemory( &wfx, sizeof(wfx));
wfx.nSamplesPerSec=11025;
wfx.nAvgBytesPerSec=11025;
wfx.nBlockAlign=1;
wfx.wBitsPerSample=8;
DSCBUFFERDESC dscbDesc;
dscbDesc.dwSize=sizeof(DSCBUFFERDESC);
dscbDesc.dwFlags=0;
dscbDesc.dwBufferBytes=wfx.nAvgBytesPerSec;
dscbDesc.dwReserved=0;
dscbDesc.lpwfxFormat=&wfx;
LPLPDIRECTSOUNDCAPTUREBUFFER pDSCaptureBuffer=NULL;
if(g_pDSCapture->CreateCaptureBuffer(&dscbDesc,pDSCaptureBuffer,NULL)==DSERR_INVALIDPARAM)
{Edit1->Text="error";
}
它总是参数错误，我真的真的找不到那里错了，程序可以执行，编没有提示错误！
而g_pDSCapture->CreateCaptureBuffer总是返回DSERR_INVALIDPARAM，我的程序执行到这里就ＫＩＬＬ了！我怎么往下写呀，请高人指点！
这是一个sound capture程序我机器装的是directx8.1SDK！ms的dsound.lib格式，我转成了BCB中的,原dsound.lib在BCB中不能调用，我的directdraw转化完都一切正常！draw部分我写完了！sound部分我是服了！服。。。。。。。。了！求助！

没有人用过directsound sdk知道吗？

最好到“专题开发/多媒体”开发版块问一下
