HDMI audio doens't work on TV

I tried to attach my tv to an old PC, so I could play movies from my computer. THe video works, but the audio doesn't.
I used a HDMI cable, got realtek driver, enabled and put HDMI as standard output. But no sound. The GPU of this computer is Nvidia gt8400.
If you need any intel I can provide you with most of it.

There were very few if any cards form the 8xxx/9xxx series of Nvidia cards that had native audio built into them for HDMI, unless they were custom made OEM models. If yours is one that doesn't then you have to do this,

Guide: 8800GT/9800GT/9800GTX Sound over HDMI (Now including Creative cards)

to get audio over HDMI from the card.

Thanks. I don't know if I will be capable of doing the stuff in that guide though, I'm not that good with building computer and never done it myself.
But now I atleast know what the problem is. Thanks again.

one hdmi connection on the tv will have audio sockets associated to connect the pc audio out (green socket) to mini socket on the tv.

Yep usually an HDMI input can be used with analogue audio from the PC audio out. Sometimes you may have to tell the TV to use that audio on the HDMI sometimes it auto senses.
On this TV the HDMI # 2 can have anologe audio on it, take a careful look on the back of your TV.

Well my TV has 2 HDMI inputs, but none of them have audio sockets/jacks, however my Tv has a fourth input channel (3 scart, 2 hdmi and this one) It has a couple of jacks, but is shows up as extension 4 on my TV. Would it work if I plug the audio cable from my PC into that one?

Hi Provide the make and full model number of your TV and I'll research it for you.

HIer is the webpage of its producer on it data page. 26PFL3512D/12 Philips breedbeeld Flat TV 26PFL3512D 26 inch LCD-TV met geïntegreerde digitale tuner met Digital Crystal Clear - Philips Support It is Dutch, but there is no english page. I also added a picture of all its jacks.

Found an English manual online, WOW what a nice little TV. Could have done with one of these 20 years ago. Picks up everything you could throw at it in Europe. Not like the old days.....Still yes it can be done see below from the manual.

30.1 Connecting the PC equipment
Important
For the TV to function as a PC monitor, the following steps must be taken.
1 Connect the DVI output of your computer to the HDMI 1 or HDMI 2
connector of the TV. Use a HDMI to DVI cable if the DVI output is to be connected.
2 Connect the audio cable to the PC’s Audio jack and to the L / R Audio jacks (EXT3) of the TV.
3 Press the key to display Source List and use the Î ï key to select HDMI 1 or HDMI 2.
4 Press the Æ / key to switch to the selected source.

So you need a 3.5mm (PC end) to RCA / Phono RED WHITE Plugs cable. Like this

So I need a HDMI to DVI cable, right? I can't use the HDMI cable from HDMI PC to HDMI Tv? And then just put the audio output on my PC to the audio jack?

No you need an HDMI to HDMI cable unless you want to take DVI from the PC. Does your PC have an HDMI connector? The HDMI to HDMI cables are generally cheaper. If your PC only has a DVI then get a DVI to HDMI cable.
The manual says to use DVI to HDMI as it is only recently that all most all video cards have HDMI as a standard now.
