Question to clarify: Does this bug still persist if you simply turn off hardware acceleration of sound and set mode to "Windows XP" or lower?
That wouldn't help, because there are actually DLLs missing. They're called "x3daudio1_*.dll", "xactengine2_*.dll", "xapofx1_*.dll" and "xaudio2_*.dll". Drakensang for example refuses to start due to the missing DLLs unless you suply the native versions.
My understanding is that these DLLs are part of the newer DirectX packages (somewhere from June 2008 onward).
