Posted this on opera forum got 1 answer basically saying is the plugin enabled? Does anybody have the same problem with this? When flash videoes are played (ie youtube) sometimes no sound is played . Win7 64 bit I have not tried 64 bit flash as of yet plus a simple uninstall of Flash Player 11.3.300.262 and reinstall of the previous version does not get sound back only system restore does. Ps opera is run in CIS manual sandbox.
