At least some bad versions of the game are still being distributed as recently as yesterday, the 12th. I downloaded and installed the game yesterday AM, and experienced the sound and crashing issue. I did log a support request, but have not heard back yet.

However, after reading this thread, I installed Galaxy, and the version of the game distributed through Gakaxy works fine. I was hesitant to install Galaxy earlier, since it is still in Beta phase.

It is disappointing, though, that at least some bad versions of the game are still being distributed, to people that don't use Galaxy, and this issue still needs to be addressed by the gog.com team.

The series of events for this issue is basically this::

-Steam released the game, had broken sound issues.
-Gog then released the game, sound issues fixed.
-Gog version got de-listed for sale.
-Steam version finally gets fixed after months of being broken.
-Gog version comes back on sale but with the old broken version.
-Gog version is now fixed.

Needless to say these series of events are BS and terrible.
