sound with my asus a7v-133 integrated soundcard keep skipping..HELP!

[sml160]

That about sums it up...whenever i play anything it kind of skips or pops a little bit...I've tried different speakers (even though i knew this wasn't the problem)...I've tried to update the drivers since it doesn't give any directions on how to do it on asus' webpage...i tried to do it manually but it tells me the best driver is already installed...

any help would be greatly appreciated...i just want clear sound...is that to much to ask for? (HA!)

thanks!
