dx9 doesnt have much to do with audio heh. look at doom3, it's openGL, and is supposed to have some of the best 5.1 surround sound. who would have thunk ;)
bottlnecking will effect fps, but only 25 fps? and with a x800 in dod?!? thats a bit stretch.
try changing your resolution higher or lower and see what happens.
noooooo.
