Hi Vijay,

Functions like _CreateSoundBank, _PrepareInMemoryWave and others return 
a pointer to a new object which you aren't doing but returning S_OK to 
indication that it will be valid.  These functions should return E_NOTIMPL.

Can you please add a FIXME to DllGetClassObject if nothing matches?

Regards
Alistair.
