I got a HDMI cable today to connect my Laptop to the TV. When I connect it the picture is good (although only on the TV and would prefer it to be on both if possible) but there is no sound coming from the TV, just the laptop. In Control Panel - Sound there is a HDMI option but it states that it is not plugged in when it is. Have tried restarting etc but still no luck.
What can I do to solve these problems, any help is appreciated thanks.
