I have added dynamic load of `CM_Register_Notification`/`CM_Unregister_Notification` from `cfgmgr32.dll` since MinGW-w64 doesn't have them it in its headers: https://sourceforge.net/p/mingw-w64/mingw-w64/ci/master/tree/mingw-w64-headers/include/cfgmgr32.h

AFAIK additional HID output report request should be sent to switch between speaker or headphones output or no output. I have found [some related code](https://github.com/nowrep/dualsensectl/blob/main/main.c). See `command_speaker()` and `command_volume()`.
