sickmaggot 0 Posted January 15, 2005 Hey guys! I want to buy a Logitech Z-640 and i just want to know if i had to buy a 5.1 soundcard for my pc to use it? My audio is built-in with my motherboard so i supposed that i have to buy a soundcard first to use a 5.1 speaker right? Can I use a Creative SB Ectiva SE 5.1 soundcard. Will this work for the speaker? I dont have much money to buy an expensive one. Share this post Link to post
