Is there a way to install xaudio2 without using the large `winetricks directx9' ? I am asking because I would like to try serious sam second hd, but in a clean wineprefix it does not start asking for a xaudio2 dll. I copied that .dll inside the game directory, but the game starts soundless and it shows an error about an non-updated xaudio2. A part of the lack of the audio the game runs well... Now, using winetricks directx9 the game starts and the audio works, but the game seems much slower. So I was wondering if it possible to install xaudio2 without installing all directx9. Here is what I tried. I installed directx9 in a separated wineprefix and I copied in the game folder the files whose name is (case a part): windows/system32/xactengine* windows/system32/x3daudio* and I used regsvr32 to register the xactengine* ones. The idea was inspired by this bug report: http://bugs.winehq.org/show_bug.cgi?id=12182 But it does not work, Serious Sam still complains about the lack of an updated xaudio2. What can I try? Do anyone know what components are part of xaudio2? Thanks
