[PATCH v3 0/4] MR3554: mmdevapi: fixes for Yousician

[David McFarland (＠corngood)]

Since Yousician's last update, it was throwing an error when initialising audio output.  Unfortunately I don't have access to the old version, but they seem to have dropped win<10 support, and are using only IAudioClient3_InitializeSharedAudioStream.  They also use IDeviceTopology to get the type of the first output connector.

This is the bare minimum I needed to get it working.
