300kb? That is pretty small. But, what does it contain? You can email me a file the small easily enough though. If you have the ability to generate a patch, using cvs diff, I would be able to apply your changes. Any new files, you could zip and send me.
As for OpenAL and Fmod changes. You updated to a recent OpenAL or something? As far as I know, there should be no changes neccessary for Fmod at least, since it uses an older version; however, maybe an update is needed. But, upgrading to FmodEx is unneeded, as the sound plugins are just examples to show how one can integrate the system with their own sound systems by simply rpoviding the proper methods.
