I have no sound in youtube. Works fine in chrome or IE. I've uninstalled and reinstalled flash and Firefox galore. I've googled and messed with the registry, still no luck. I have always been someone who's been able to fix these types of problems but this one has me stuck.
Still no luck. I was running IE8, so I upgraded to IE9 (64-bit). Flash is working properly in both IE and FF, according to the site above. The only flash thing that I see is in my control panel, where it says it is 32 bit.
