I have a HP Pavilion ZX5000 Laptop with Windows XP. I bought it used without a Sound Device and no restore disk for it. The former owner couldn't get it to work either. I downloaded the one HP has on their website for it but it just makes the computer freeze the moment it tries to make a sound. I don't know if there is a driver I need to get it to work or if that's just the wrong sound device or what. Any suggestions would be appreciated, thanks.
