XP customised installation missing sound

Hi, today I managed to create a Windows XP Home Edition service pack 2 customised installation disc and have XP on my laptop now. My laptop is an Advent 5611 and originally had Windows Vista, but after a hard drive failure, I had to replace both the hard drive and operating system. My only issue is I have no sound at all, and from what I've gathered online, I need to get a sound driver I think. I have no idea what I'm looking for, or if it's something I even need to download, or do I just need to find the driver and make a new installation disc with it included? I'm happy to do that, as long as I get sound! I have no idea what I'm searching for, so if anyone knows where I can download the driver that I can put into a new installation disc, or even just what I can do as an alternative, that'd be great

 

Ahh that did the trick, thank you!
