The problem is likely that the game uses WMA/XMA audio, and the Win32 port of FAudio uses Media Foundation WMA decoder transform for that. Wine's Media Foundation doesn't currently implement any decoder transform.
Does this mean that all sounds would stop working, or only sound mixing? Not sure if it's relevant, but in Skyrim's case (duplicate bug 52512) only some sounds don't work while others still do.
