hdmi cable to LG tv no audio

i have my pc connected to a LG flatron 22" tv by hdmi cable the picture is fine but the audio does not play through the tv, a jack cable from the pc to the tv does not work either, if i use the jack plug into separate speakers it will play the audio through the speakers. i have checked in play back devices that the tv is default device, checked audio and graphics card drivers they are all up to date.

pc specs are:
cpu: amd phenom ii x4 BE 3.4ghz
mobo: asus m4n75td
graphics card: 2 x nvidia gefore 8800 gs in sli

stuck on what to try next any help would be appreciated

Hi all
A have a problem
My LCD TV (LG 32 LD650) do not play audio
I connect my notebook HP Pavilion g6 and TV via HDMI
Video shows in resolution FullHD
Screen's duplicated (win-P)
speaker icon in the right corner of the display with a red cross, when you hover the mouse on it pops up message "No audio output device detected"
In the properties "Control panel - Sound" also no audio volume (see attach)
May be my video card do not support transfer audio stream? or TV not supported speakers?
AMD Catalyst latest version
