PCM Stream Data Format
This example uses a KSDATAFORMAT_WAVEFORMATEX structure to describe the data format of a PCM stream.
DataFormat.FormatSize = sizeof(KSDATAFORMAT_WAVEFORMATEX);
DataFormat.Flags = 0;
DataFormat.SampleSize = 0;
DataFormat.Reserved = 0;
DataFormat.MajorFormat = STATICGUIDOF(KSDATAFORMAT_TYPE_AUDIO);
DataFormat.SubFormat = STATICGUIDOF(KSDATAFORMAT_SUBTYPE_PCM);
DataFormat.Specifier = STATICGUIDOF(KSDATAFORMAT_SPECIFIER_WAVEFORMATEX);
Format.wFormatTag = WAVE_FORMAT_PCM;
Format.nChannels = 2;
Format.nSamplesPerSec = 44100;
Format.nAvgBytesPerSec = 176400;
Format.nBlockAlign = 4;
Format.wBitsPerSample = 16;
Format.cbSize = 0;
