You shouldn't think of being able to compile the microsoft minor includion.
Open the source code, which is the developper any starts.
Data structure is different only, from 64bit Windows.

Sounds device id has changed so many times and we can hear that sounds well on windows. But that includes "mmdeviceapi.h".

souds device id:
msg_buffer m_waveout device is |10182672|. -> |9B6010|
msg_buffer m_waveout device is |9271320|.  -> |8D7818|
msg_buffer m_waveout device is |8097776|.  -> |7B8FF0|
