Internet Browsers' Sounds Not Working.

Hello,

I am on my Asus and have had this laptop for quite a while, Windows 7 i3.
Up until today my laptop was fine, I can listen to anything on any browser just fine. Specifically I decided to watch videos today on youtube. But none of the sound was working. I began seeing if it was just youtube but google had a doodle today with sound, i realize it was that too. So I am assuming it was just Google Chrome, but it was also Safari, IE, Mozzilla as well. So the Symptoms were, like most other posts:

*Sounds not working, IN ALL BROWSERS.
*Exceptions, occasional videos after many refreshes work, then after playing it again doesn't work.
*Also when I do get a video to work out of MULTIPLE REFRESHES AND VIDEOS buffering playing soundless, the sound still does not work.
****Note this is like the other forum situation. I have tried as much as I can, the missing.reg idea doesn't seem to work. the RESET IE worked slightly, having allow me play one video in IE, but like i said, as I tried multiple videos it just shuts off ALL BROWSER SOUNDS. I see this has been a problem for years and hope someone can fix this.

*** Also note, I tried missing.reg, reseting IE, of course my volumes are all fullblast as well, and etc.
*** As with anyone else, this is just in browsers, skype was fine, league of legends games etc. was fine, as well as other media players.
