With built-in Xaudio the game starts and shows a couple splash screens, then it
crashes when loading to the menu.
> err:ole:CoGetClassObject class {e21a7345-eb21-468e-be50-804db97cf708} not registered
> err:ole:CoGetClassObject no class object {e21a7345-eb21-468e-be50-804db97cf708} could be created for context 0x1

On a Windows XP machine with Directx installed I looked up the relevant uuid,
it belongs to xaudio2_1.dll:

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID{e21a7345-eb21-468e-be50-804db97cf708}]
@="XAudio2"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID{e21a7345-eb21-468e-be50-804db97cf708}\InProcServer32]
@="C:\WINDOWS\system32\XAudio2_1.dll"
"ThreadingModel"="Both"

'winetricks xact_jun2010' is a workaround.

To reproduce the problem with the demo version:
Install the demo and skip Directx installation. Install native d3dx9_36.dll and
launch Flock.exe (it takes 15-20 seconds until the first splash screen
appears).
