No sound on flash movies

[UserLoser.]

I have both IE and Firefox installed.  For some reason, don't know when/why it happened, but recently I no longer hear audio in flash videos/movies (such as http://www.badgerbadgerbadger.com and much more).  I've tried reinstalling everything from macromedias website, no luck.  Yes, my speakers/microphones are plugged in.  Any ideas on why I don't hear anything in these movies?

Tried reinstalling your soundcard drivers?

Did you uninstall the macromedia stuff before you reinstalled it?

I assume you're still getting sound from non-flash stuff?

Due to the "Yes" answers to the other questions -- it's worth a shot, no?

Don't think they need to be upgraded/fixed, seems since i installed firefox that it's been like this, maybe i'll try uninstalling it
