Message-Id: Date: Fri, 3 Jul 2020 10:38:50 +1000 In-Reply-To: References: 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.
