Hi everyone,
I am working on creating adaptive audio for a DX game and I am using
direct music to handle all of the aa. I was wondering if it was ok to
use direct music for all the sounds in the game i.e gunshots or if I
should use direct sound to deal with the small one off stuff...

Oh FYI, the point of the C++ Autodownload is to make life easier on the
programmer. It means he doesn't have to load and unload every segment
he
calls play on. It's all handled automatically.
