What cable are you using? A 3.5mm plug to 3.5mm plug or a 3.5mm plug to red and white?

Also, are you sure you're using the right audio inputs on the TV? Because you're using the VGA connection you probably have to use a specific set of red and white inputs to get sound.

It's a 3.5mm plug from laptop's headphone jack to a red and white in my TV.

The red & white plugs are probably for aux AV inputs (L&R sound and composite video) of the TV and will be active when you select that input on TV. I don't know what audio input option you have when VGA video is selected on your TV.

The red & white part of the audio cable is currently plugged into the side. I have tried the red & white jacks at the back of the TV too and still no sound, but the video via VGA cable is perfect.

Looking at the instruction manual, it looks like to need to use a 3.5mm to 3.5mm instead.

Interesting - I just bought this cable an hour ago and they said the red & white/3.5mm would be fine. Do you think a 3.5mm to 3.5mm would DEFINITELY work?!

Without actually seeing the TV and using the instruction manual as a guide, I think so.

I just tried a very small audio cable and the bars next to Digital Audio (S/PDIF) were going up and down but still no sound coming from TV once again.

Explain "very small audio cable" and "bars next to Digital Audio." You're going to need to clarify.

You can also try posting a picture of the connections you currently have.

Audio cable was just a cable like a 3.5mm to 3.5mm but it's about 15cm long so very hard to plug in! I plugged that from my laptop headphone jack to TV's headphone jack and nothing worked once again.

Unable to post photos at the moment but if you go to: Control Panel, Sound, Manage Audio Devices under 'Playback' there are two options 'Speakers' 'Digital Audio (S/PDIF) underneath. At the moment whilst either red&white cable or the very small cable I just plugged in, next to the option in the Playback tab, whilst the audio was playing, there were green bars indicating there is sound available to play....but yet it chooses not to.

So the bar next to the Digital Audio selection is going? Is that set as the default output when the cable is plugged in?

Yes that's correct. It was like that when the first cable was plugged in too though, not just the short cable.

If you connect the laptop headphone to the TV headphone jack you won't get any sound from the TV. Because TV headphone jack is an output jack not input jack.
