I'm experiencing problems with sound in Flash Videos.
It started under Chrome browser and is now in Firefox as well.
Chrome: Version 23.0.1271.97 m
Flash version (under firefox->addons->plugins): 11.5.502.135
Windows: 7 Home Premium SP 1
I tried installing codecs (k-lite), deleting Appdata (both Macromedia & Adobe) folders, Emptying the Temporary Internet Files..
Nothing seems to work.
