--- Comment #13 from Ethan Lee flibitijibibo@gmail.com --- As long as the output sample rates match when calling SetOutputVoices after SetEffectChain it should be okay, otherwise that’s an error even in XAudio2. I was also able to verify that LockForProcess is called during SetEffectChain (or voice creation, if a chain is passed).
