Research direction
Start with line 21 in XAudio2Helpers.h and line 92 in HolographicVoiceInputMain.cpp, then reproduce the clean Debug build on HoloLens gen1. Check the XAudio2Create failure and XAUDIO2_E_INVALID_CALL result in the sample's voice-input flow. Done means the sound object initializes and the cube changes color from the voice command.

Description
Clean pull builds and deploys to Hololens gen1 from MSVS 2019. The app comes up and I see a yellow cube. It responds to taps fine. "Hey Cortana" is working so the microphone is listening. However I cannot change the cube color by command. Building in Debug and stepping through the program I found line 21 to fail in XAudio2Helpers.h
auto hr = XAudio2Create(&xAudio2Instance, XAUDIO2_1024_QUANTUM); This results in m_speechSynthesisSound not being initialized on line 92 in HolographicVoiceInputMain.cpp.
https://docs.microsoft.com/en-us/windows/win32/xaudio2/xaudio2-error-codes gives the error XAUDIO2_E_INVALID_CALL but the doc isn't helpful other than pointing invalid parameters were given.
