What's the make and model? It would be useful to know so that people can be sure to avoid it if they're thinking of buying a flat-panel (unless they're happy to run the audio through a separate amp).
It most certainly *is* misinformation when people are told "you can't get audio through the TV speakers if the video is going via HDMI, you have to use the PC input instead" as if it's some kind of universal fact that applies to all TVs.
I believe what was said was "you're going to need VGA to get audio+video simultaneously through the PC input" but whatevs.
