Sound Quit in Web Browsers

I am not sure what happened. I was peacefully having a great time using my laptop (Dell Latitude D830) when I decided that I wanted to swap over to KDE instead of Gnome since it is easier to keep track of what desktop I am on. I can set each screen for each desktop as a different wallpaper… Anyway, now my sound doesn’t work in my web browsers with any regularity and had become quite sketchy; Konqueror, Firefox, Opera. Right now, I had to use Konqueror to get to play and I am fully not sure how it suddenly worked. Firefox keeps locking up for any online sound content and Opera just sits there without sound…

If I could get some help, I would appreciate it.
