Iv been using my laptop to play through tv in bedroom via hdmi and all been fine, I reformatted laptop back to factory settings but now have no sound via tv just through the laptop. Iv done all the usual checks and if I take laptop to downstairs tv it all works fine, Iv swopped cables around and there fine, iv even used the a bluray player in the bedroom and fine so its not the hdmi cables or the sockets on tv. Tried absolutely everything ,Please help thanks!

Have you re-installed the graphics driver properly after your OS reinstall? There is usually a special driver for the protected sound path on HDMI cards. It should be included with the graphics driver, but installs as a seperate driver...
