Sound Blaster Live 5.1 SB022 Driver

i have a friend running 7 with a sound blaster live 5.1 SB022, Its running with some XP driver but not without its problems, it seems that his sound output starts to crackle then fade, So im thinking that he needs a better driver,

now i was trying to explain about using windows built in chip set drivers but nether of us are sure what drivers to use or even sure of the actual Chipset used so im asking for your help before he loses hope in 7, We know its a very old card< about 10 years old or so but we are hoping that someone has a welcoming solution with a nice driver..
