--- Comment #9 from Tom B tom@r.je --- Schmackbolzen over at the frelancer fan site the-starport.net forums figured it out: The problem is missing msacm32.dll, winetricks msacm32 solves the problem.
I'm not sure if requiring a DLL override counts as resolved but it's certainly fixed from my perspective.
