DSound bug in 'DuplicateSoundBuffer'

[Robert Reif]

I'm in the process of auditing and cleaning up the error propagation
and checking in direct sound right now trying to locate problems in
the maxpayne game and have found and fixed a few errors already.  I'm
tracking down another or possibly the same 3d buffer error right now.
I hope to have a patch out in 24 hours.  Would you be willing to try it
out first before I release it to the list?
