I've had similar issue before with a USB wireless card , error 10 , turned out to be a hardware issue , did all the same things that the OP has tried to get it working...ended up buying a new one which then worked just fine.
I'd adding my vote to hardware issue , buy a cheap compatible sound card instead.
I wouldn't give up yet on the hardware. One other thing I've seen help is reinstalling the Intel Motherboard Chipset Drivers. One of the things the chipset drivers do is identify all the devices. I've seen reinstalling chipset drivers help in some other cases. Whether it will help here? but worth a try.
Good call Fireberd: I hadn't thought to recommend that. Funky, outdated, or corrupted chipset drivers can mung all kinds of other system capabilities, including audio. Thanks!

Thanks for replies everyone.
Looks to be a hardware problem, funny how I found out. Went out for a few days and left the laptop alone, came back and it worked. Then it died again when I moved the screen angle. So if I jiggle the laptop around and change the angle of the screen I can get the sound going haha :)
Anyone know if that's just a loose cable or it needs a solder or something? And approximately how much that'll cost me?
I'm overseas at the moment so if it's easy and cheap to just get it done here instead of sorting out the warrany I'll do that.
Usually speakers are on a cable. It will require disassembling the laptop to get at the connector(s). Reseat (unplug then plug back in) the connector(s). Also, many laptops have a small "daughter" board for audio or audio I/O that plugs into the main motherboard. That is another possibility.
Hmm OK. I might unscrew the base and see if I can find anything dodgey looking (I know that voids the warranty but I need my sound back!)
Cheers again everyone for your input!
Many Laptops require access from the top to get to the speaker cables. The bottom may not get you anywhere.
Then again, if its in warranty let whoever is the warranty service provider fix it.
