Call of Duty: Black Ops

What works

Singleplayer missions.

What does not

Sound seems not to work, except for some background noises. But I managed to get it working... Somehow...

Workarounds

I tested using a 32-bit WINEPREFIX.

There seems to be several ways of getting the sound to work correctly in this game. There's a bug report in which people suggesting that it could be a problem with all things dsound. My approach was a different one, though. After running:

winetricks xact

I got several regsvr32 errors... Then, after hours and hours of head bashing, I simply had the idea of cat'ing the hell out of the dll... Particularly xaudio2_8.dll, which, according to the Wine terminal output (with WINEDEBUG=+all), the game had been struggling with. Turns out it was only a reference for the builtin library (thus the dsound fix seems to make a lot of sense, considering we're dealing with an internal Wine implementations). Nevertheless, it simply won't work.

So I downloaded a 32-bit version of xaudio2_8.dll from a random DLL deposit I found, by Googling for the aforementioned xaudio2_8.dll. Then I moved this file to the WINEPREFIX system32 directory and regsvr'd it:

WINEPREFIX=... WINEARCH=win32 wine regsvr32 C:\\windows\\system32\\xaudio2_8.dll)

I got no errors from this command. Then I've instructed Wine to use the xaudio2_8.dll as native only, and bam! I got sound working correctly.

What was not tested

Zombies and multiplayer.

Hardware tested

Graphics:

• GPU: Nvidia

Additional Comments

Try a clean WINE prefix (I think it's not necessary)

Install Directx from the CoD:BO game directory.

Set winever to XP.

Set dsound to builtin.

I use ALSA with full hardware aceleration.
