HP Pavilion G6 Audio :: On And Off Randomly?

HP Pavilion g6 Notebook PC.
Windows 8.
 
So I've had my laptop for roughly around 9 months and I have started having trouble with it about 2 months after I got it. Although it may not be entirely the laptops fault as I think the person who sold it to me just wanted a quick sale because it does the bare minimum of what I expect it to do.
 
But lately to my great annoyance the audio has stopped working...for everything. Nothing I've tried has worked and every so often it will at random the sound will be back on again. It's done this on occassion about 5 months after I bought it and I didn't think anything of it but now it's happening everday and is driving me nuts!
 
I've tried uninstalling the sound and restarting but that doesn't do anything double and triple checked that nothing is on mute, I've used VLC, youtube and Windows Media Player to test it out and still nothing. In the control panel it says the sound is working but it's not. I've also tried putting in headphones and there isn't any sound from the headphones either.
