No Audio on YouTube

My audio suddenly stopped working about 2 weeks ago on youtube and now only works when I plug in headphones. Audio is all other applications works without headphones. I have already: 1) Updated Adobe plugins 2) Restarted computer 3) Ran virus scan and malware scans 4) Checked Adobe manager settings 5) Checked audio levels in other applications (Windows Media Player, Songbird, etc) 6) Checked audio levels/mute button in youtube 7) Checked Sound settings in Control Panel

I have not installed any new hardware or software except for security updates. I'm using Firefox 3.6.8 on a Win 7 machine.This seems to only effect videos in Firefox. Videos in Explorer work without headphones, but that is not my preferred browser.
