hi guys, i have my pc on my tv connected through hdmi . i also have sky and my blureay player connected through hdmi as well. if im watching sky for example and then press the remote to go to pc channel i have no sound from the pc hdmi input, i have to unplug the hdmi from the tv and plug it back in and then i get the sound. this does not happen when i go from sky to dvd for example, its only when i select the pc input . i have chasnged round the hdmi inputs on tv and whatever hdmi socket i put the pc input in, its the same. could this be be a driver issue as im sure i have latest drivers. or could it be a cable issue .not really sure myself, any thoughts be good
