Did you look in Device Manager to check for driver errors?
If you didn't download the driver from the HP website it will be the wrong one. Only HP have the correct drivers for their own laptop models. HP United Kingdom drivers page is here: http://www8.hp.com/uk/en/drivers.html
For other countries click the United Kingdom flag at bottom-left of HP page.
If the sound works using headphones, your speakers could be bad. If you only tried the internal speakers, check with a set of external ones, but since they would be using the same headphone connection as the headphones they should work fine.
