Karmic - Youtube videos gooble 100% and no sound and acts as if it's Fast Forwarding

[Theatre-X]

Binary package hint: firefox-3.5

Whenever I play Youtube videos, Firefox suddenly starts eating CPU cycles and the CPU usage shoots up to 100%. If I rewind the video (Normally because it hasn't loaded enough of it yet), if the CPU cycles are at 100% there is no longer sound unless I close Firefox or the Tab that Youtube is in. I've even had videos slightly fast forward and there is no sound as well.

Weird, huh? :)
