--- Comment #6 from Andrew Eikum aeikum@codeweavers.com --- openal32 isn't included in the Windows OS, so games must distribute it anyway. Wine's built-in openal32 was introduced because native openal32 did not work in Wine's audio system. Now it does, so there's no need for us to ship a built-in openal32.
