subwoofer not working

[nighthawk101]

Well I hook my z5500s back up and the sub decides not to work. Its not receiving ANY signal... at all. This seems to be a widespread problem with my motherboards audio codec(i9880). I am basically having the same problem as this guy. http://www.cmedia.com/forums/viewtopic.php?t=60


I thought that I should just buy a sound card, but people on that forum have said that they tried that as well and still no luck. Any suggestions?
