I have a Toshiba Satellite Laptop Model P745-S4102 with Intel integrated graphics and Ubuntu 12.04 LTS installed recently. When I connect my HDMI TV to it I only get video through it and no audio. In the System Settings -> Sound, there is no option to select HDMI as the output. I read other threads in this site and it seems like at least guys had HDMI option but no sound. I don't even get that.
