Hello Pankai, hi check cable connections, the speakers connection is on the green port of your speakers. if its fine. Now check if the sound card was detected by your computer, check device manager and see if your sound card is present ( no yellow ! and ?). If you find a yellow symbol on your sound card, needs the device driver, (locate your CD driver) install the device driver for your sound card. if you cannot find the driver CD, visit the manufacturer's website and download the driver. if your sound card is part of the mother board, visit the motherboard's website and find your driver there. you need the motherboard model.
