Windows 7 = No sound

Been searching for an answer for hours on this and I can't seem to find a straight answer...anyway, I just did a clean boot of Windows 7 today, from Windows XP. Now, there's no sound coming through my speakers...I can only assume it's the drivers, but I have no idea what drivers to get or indeed if I need them at all? Help would be appreciated! :( /n00b

Well your missing drivers, but a bit info would help.

Do you have a seperate soundcard or are you using the one on the mobo?
