Sorry to hear it did not work (already update)
Not sure what you have done thus far. As far as settings go; in control panel/sound, is HDMI output recognized (is it there)? If so, make sure it is set as default device (by right clicking on it). You could also try unplugging and plugging back in the HDMI cable while the TV and PC are both turned on (this may allow the PC to recognize TV). I am not a super-tech-type, so this is about all i have for you at this point. Good luck
