Laptop, desktop, mainframe ?
Maybe post model number and some details like 'it never worked, it used to work but i upgrade to win7 and it stopped, it just stopped, it works for windows sound but not media center, it stopped when i put in a new video card and win7 defaulted to HDMI sound instead of my sound card, it stopped when i started using USB attached gaming headphones and win7 defaulted to teh headphone as the output devce, it stopped when i dropped the laptop on the floor... " you get the concept. "Can you help me to get my speakers to work on my computer" needs a bit more detail.
