No sound on v5.3(any files)

[nitrous991]

i was getting audio from avi and mp4 now it doesnt play sound i tried the swf file thing but it wont even load the file maybe re-installing would fix? so now im stuck with WMP till this is solved i uninstalled ffdshow and put in CCCP but still nothing. Also i dont think that tversity has to do anything with it because its never had an issue before
