XAudio2 Error Codes (xaudio2.h): 0x88960001

Returned by XAudio2 for certain API usage errors (invalid calls and so on) that are hard to avoid completely and should be handled by a title at runtime. (API usage errors that are completely avoidable, such as invalid parameters, cause an ASSERT in debug builds and undefined behavior in retail builds, so no error code is defined for them.)
