No sound with my HDMI cable

I just bought a new LG 55lv5500 TV last night, got everything plugged in and working but today I tried playing my Xbox 360 for the first time and as soon as I turned it on there was a update so I updated it. I now have no sound with it on my TV but my video is working just fine, I have tried using other HDMI ports on the TV and other HDMI cables. Nothing is working, I have read on forums where they say go into system setting and under video turn off discovery but I don't have discovery as a option any where on my system. so someone please offer me a solution to this problem.

I have the same problem but with a Bravia TV, except when I turn it off I still have no sound, used 2 different cables and tried all different HDMI ports.
