No sound when playing media from your laptop through TV
Connected your laptop to your TV via an HDMI cable and getting pictures but no sound? It’s a common problem that's easily fixed. Press Windows key+R to open the Run box, type mmsys.cpl and press Enter. Select the Playback tab to view a list of available devices, which should include an entry for your TV. Right-click this entry and choose ‘Set as Default Device’. Click OK to close the box and then, if necessary, close and restart whatever media application you’re using to output audio/video to your TV.
