Hi there,

 

I'm using DirectSound to read in data from the default microphone and hand it off to Wwise (AudioKinetic's sound engine).

 

HRESULT result = DirectSoundCaptureCreate8(&DSDEVID_DefaultVoiceCapture, &myDirectSoundCapture, NULL);

...

// Generate the capture buffer description
DSCBUFFERDESC bufferDescription;
bufferDescription.dwSize	= sizeof( DSCBUFFERDESC );
bufferDescription.dwFlags	= 0;
bufferDescription.dwBufferBytes = myWaveFormat.nAvgBytesPerSec;
bufferDescription.dwReserved	= 0;
bufferDescription.lpwfxFormat	= &myWaveFormat;
bufferDescription.dwFXCount	= 0;
bufferDescription.lpDSCFXDesc	= NULL;

LPDIRECTSOUNDCAPTUREBUFFER captureBuffer;

HRESULT result = myDirectSoundCapture->CreateCaptureBuffer( &bufferDescription, &captureBuffer, NULL );
if( SUCCEEDED(result) )
{
  result = captureBuffer->QueryInterface( IID_IDirectSoundCaptureBuffer8, (LPVOID*)&myCaptureBuffer )
}

 

 

 

After initialization, when I actually start reading in data from the microphone the sound levels in Windows (everything in windows) drops by about 15db... you can barely hear anything. At the moment I call myCaptureBuffer->Start( DSCBSTART_LOOPING )

 

Anyone experienced this before or know of a solution?

I've tried changing the device that I'm connecting to:

 

* DSDEVID_DefaultCapture the sound levels are fine but I'm getting feedback coming through the headset (despite the fact I'm not outputting any audio)

* GUID_NULL the same thing as DSDEVID_DefaultCapture

Ah - when you connect to DefaultVoiceCapture, there is a setting in Windows that reduces all other audio by 80%
