Well, the docs say it does, though ANY window is fine according to
them. I'll just have to try it out. I also think that you can get the
HWND to a console window, but I could imagine situations when there's
none of those either.

Don't worry, I won't. I think you do pass a HWND of a newly created
(but not shown) window to SetCooperativeLevel in vo_directx though
(created around line 980, used then in Directx_InitDirectDraw).

By the way, what should I call the new ao? ao_dsound or ao_directx?
Or maybe even ao_directsound?

One more thing: How does MPlayer exactly find out that the audio
stream has reached its end? Does it wait until get_delay returns
zero? Or does it use its own timer to find out when to stop?
