I have lost all sound on the internet (or has someone turned off the main switch??). I still have sound through the speakers (ie email alerts), but none through the internet (ie youtube etc)

Any ideas what I might have done or what I can do to sort it?

Thanks

You need to think in Russian.

Oh, sorry.

Try reinstalling the Flash plugin

Does it work OK in IE?

sometimes the obvious things – has the volume within YouTube been turned down or muted?

Had checked the volume thing, not sure how to reinstall flash player, but turned out I didn’t have the latest firefox. Installed that and problem solved
