GetForegroundWindow() doesn't necessarily return the own window handle. It just returns a handle to the currently active window and can even return NULL. At the time dsound_open() gets called the active window is most likely the shell window and not the QEMU window. Replace GetForegroundWindow() with GetDesktopWindow() which always returns a valid window handle, and at the same time replace the DirectSound buffer flag DSBCAPS_STICKYFOCUS with DSBCAPS_GLOBALFOCUS where Windows only expects a valid window handle for DirectSound function SetCooperativeLevel(). The Microsoft online docs for IDirectSound::SetCooperativeLevel recommend this in the remarks. This fixes a bug where you can't hear sound from the guest. To reproduce start qemu with -machine pcspk-audiodev=audio0 -device intel-hda -device hda-duplex,audiodev=audio0 -audiodev dsound,id=audio0,out.mixing-engine=off from a shell and start audio playback with the hda device in the guest. The guest will be silent. To hear guest audio you have to activate the shell window once.
