Hi I have this big problem, I connected my computer to my TV with hdmi cables to watch videos on computer, on the tv I switch the input to hdmi I see the video really great but my sound is from the TV program. I also connected a audio cable from computer to tv. In the sound properties on computer under playback I see picture of my TV but says it is unplug and cant set is as default. Can any one help me its driving me crazy. Thanks
