MY screen has VGA hooked up from my graphics card to the TV. Is that why there is no sound? Other than that I put the TV as default sound and no sound.

If your TV doesn't have HDMI input, you need a separate cable from th Computers sound ports to the TV for Sound.

your post doesn't make sense!!

"Hooked up HDMI port and no sound"
"VGA hooked up from my graphics card to the TV"

[dustyjay]

If you are not connected to the TV with HDMI you wil get no sound from the TV. If you are connected to the tv via a VGA cable you will have to set your computers sound card as the Default Audio and use either Speakers conected to the computer for sound or if yur TV has Audio inputs a Cable between the Speaker port on your computer and the TV.

Also if the computer you are talking about is the one in yur Specs, the specs lack useful information. Please post your system specs, To include Make and model System if Big Box, or same info for the following if custom or home built, Mother Board (including Revision number), Processor (Exact Model Number), Ram, Video Card, Hdd(s), Optical Drive(s), Power Supply Manufacturer Model, Wattage and Amperage on the +12V Rails, OS, and any other peripherals installed on the motherboard.

@ replay I can't see how it doesn't. I hooked up a hdmi port from computer to TV and there is no sound. and I hooked up a vga cable from TV to my Graphics card...

@dustjay I've been meaning to change them but I don't know the website well yet. Also It has 2 HDMI port inputs and I plug them into either one and switch the input and my screen goes black. Corse It's not plugged into my graphic card. (radeon 6990) So...Can I not use this hdmi for video and sound?

the hdmi will carry audio and video to the tv
do u have the hdmi out set as default....see pic (mine is not)

[turbow5]

Yes and when I play music the bar moves but there's no actual sound, and no its not on mute or low volume.

Connect the computer to the TV with the HDMI cable. Nothing else. No VGA cable. You can't have both.

[dustyjay]

You should be able to use the HDMI for video and audio on the TV. Are you saying you get no Video or audio from the TV when using the onboard HDMI. Run this and it will give you the TSG Hardware specs http://static.techguy.org/download/SysInfo.exe

It says no signal when the VGA is unplugged. and the HDMI is plugged.

Does the TV support computer inputs via HDMI? Did you read that in the TV's manual?

[dustyjay]

On all my LCD tvs I have to select which input source I am connecting to, whether VGA or HDMI. Of course I assume you have been there, but just have to check.

[turbow5]

@doublehelix Yes I have read the manual and no luck.
@dustyjay yes, I select input > hdmi and then it just says the no signal thing.

Have you tried a different HDMI Cable just in case the one you have isn't working. I have had only one HDMI Cable that was bad, but it can happen.
