[DotNetDevelopment] DirectSound throwing "Error in Application" - C# DirectX Programming

[mehstg1319]

Hi there

Have been totally pulling my hair out with the above error. It is
occuring when I try to initalise the capture buffer as follows:

dxCaptureBuffer = new CaptureBuffer(dxCaptureBufferDescription,
dxCapture);

Maybe somebody else can spot something I am missing, as I have spent
hours trying to figure this out to no avail.

Capture Buffer Description code:

            dxCaptureBufferDescription = new CaptureBufferDescription
();
            dxCaptureBufferDescription.BufferBytes =
wavFormat.AverageBytesPerSecond / 5;

Audio Device code:

            //Initalise the DirectSound device
            dxSoundDevice = new Device();

            //Set cooperative level from form control.
            dxSoundDevice.SetCooperativeLevel(control,
CooperativeLevel.Normal);

            /**
            * The following code sets up the format of the Wav
capture.
            * Format is as follows:
            * PCM audio - 22KHz - 16bit - Mono
            **/
            short channels = 1;
            short bitsPerSample = 16;
            int samplesPerSecond = 22050;

            wavFormat = new WaveFormat();
            wavFormat.Channels = channels;
            wavFormat.FormatTag = WaveFormatTag.Pcm;
            wavFormat.SamplesPerSecond = samplesPerSecond;
            wavFormat.BitsPerSample = bitsPerSample;

            /**
             *     BlockAlign is the minimum atomic unit of data
             *     The value of the BlockAlign property must be equal
to the product of Channels and
             *     BitsPerSample divided by 8 (bits per byte).
             **/
            wavFormat.BlockAlign = (short)(channels * (bitsPerSample /
(short)8));
            //Average bytes per second = block align * samples per
second.
            wavFormat.AverageBytesPerSecond = wavFormat.BlockAlign *
samplesPerSecond;



Thanks in advance, hopefully somebody can put an end to my DirectX
misery :-)
