Another possibility is that this initialization is a side effect of dsound creating a window internally. We have this thing implemented in imm32, and as I recall it was possible to test by disabling IMM with some user32 function.

Unfortunately, your assumption doesn't seem to be correct.
I have manually tested using SetWindowsHookEx(WH_CBT and HCBT_CREATEWND) and confirmed that dsound initialization does not create any windows other than the OleMainThreadWndClass window.

Reading ImmSetActiveContext() in dlls/imm32/imm.c, it initializes COM with the COINIT_APARTMENTTHREADED parameter, not COINIT_MULTITHREADED.
My test shows that IDirectSound::Initialize() creates a multithread apartment.
Could you share your thoughts on this point?
