No sound through hdmi

After changing my graphics card to one with an hdmi port, it plays the picture on my tv with no problems. However there is no sound. Is this becouse the sound is going through the onboard sound and not the graphics card its an old system which i am upgrading as much as poss without changing the mother board. Help me please:confused

 

Hello,
Did you set the HDMI device as default playback device in control panel

Start>Control Panel>Sound>Playback (or Audio) tab depending on the OS. Select the HDMI device as the default device. You may also have to disable onboard audio in BIOS.

Thanks ill give that ago n post what happens

 

It doesnt seem to be recognising the hdmi port. All i have is the top 2 similar to the ones in your picture

 

Do you see any yellow exclamation marks in Device Manager relating to sound? Expand the Sound devices by clicking on the plus sign.

 

Nope there is nothing at all. The graphic card is all working fine according to device manager

 

I'm sorry but I have run out of ideas. Hopefully somebody on the board can jump is with some suggestions.

 

Thanks for the help

 

I think you'll find that your card does not support audio over HDMI? It could be that they just convert the DVI to HDMI (just change the port) and not bother with linking in audio.

Post the model please

 

Its an PNY NVIDIA GeForce 8400 GS PCI-E graphics card 512mb

 

It is only a DVI & VGA port capable card. You have to use a 1/8" stereo to RCA cord for audio. Either go to Radioshack and get one, or you can get both from Monoprice.

 

As im a begginer. How come it takes the picture with the hdmi cable then?

 

Is this your card?

I could not find any user guide for it. They do say a detailed installation guide is included on the CD. Is there any mention of a setting that have to be set for HDMI on this guide?

 

Box is different but looks about right. Clicked on the manuals bit on the disk n nowt happened?

 

go to my computer and right click the disc drive and "explore" / "open" the disc, you should be able to find the manuals that way

 

Cant find anything like that that way either n theres barely a mention off windows 7
