In your client application that uses Microsoft DirectX, when you try to play back or to convert a WAV file that is larger than 2 gigabytes (GB), you may receive the following error message:
0x8004020D - The buffer is not big enough
This problem occurs because a limitation exists in DirectX. DirectX uses a signed data type instead of an unsigned data type.
