--- Comment #18 from Andrew Eikum aeikum@codeweavers.com --- I tested this today. Looks like the game uses WMA for some of its audio, which Wine can't currently decode:
0067:trace:xaudio2:IXAudio2Impl_CreateSourceVoice (0x1b1758)->(0xba4e8ec, 0x23a69bb4, 0x10, 2.000000, (nil), 0xba4e8fc, (nil)) 0067:trace:xaudio2:dump_fmt wFormatTag: 0x161 (Unknown) 0067:trace:xaudio2:dump_fmt nChannels: 2 0067:trace:xaudio2:dump_fmt nSamplesPerSec: 44100 0067:trace:xaudio2:dump_fmt nAvgBytesPerSec: 6000 0067:trace:xaudio2:dump_fmt nBlockAlign: 2230 0067:trace:xaudio2:dump_fmt wBitsPerSample: 16 0067:trace:xaudio2:dump_fmt cbSize: 0 0067:warn:xaudio2:IXAudio2Impl_CreateSourceVoice OpenAL can't convert this format!
I think this is a dupe of Bug 39402.
I was surprised to see that winetricks doesn't set native xaudio2 DLLs to native when installing the xact verb. Probably the game stopped working when Wine gained an xaudio2_6 DLL.
