There is NO sdl audio support in retail ut2004. It's OSS or ALSA, or
build your own openal.

Some people have reported that the game is opening the wrong ALSA
library. Try symlinking your libasound.so.2 to libasound.so  ...

I wish there wasn't twelve different ways to talk to sound hardware on
Linux.
