After seeing this, I decided to write my own test, and can confirm now that this
patch looks correct: after a successful LoadLibrary("dsound.dll") FreeLibrary
needs to be called 2 times before it starts to return FALSE.

Just for fun I tested other dlls as well (GetModuleHandle returns 0 for all of them
before the LoadLibrary call):
user32 requires 4 FreeLibrary calls after LoadLibrary, dinput - 1, mfc42 - 1,
advapi32 - 1, comctl32 - 1.

I'm attaching the program I used for testing.

Probably simple LoadLibrary("dsound.dll") should be enough.
