I recently bought Ca 2012 speakers for my computer.
But when i plugged them to the computer I heard no sound came out of my speakers. I checked the speakers , and the blue led light ( power button)
was on. I went to Master Volume and it said no device was connected when my speakers were plugged in the correct jack.

Then I took out the speakers , connected them to my CD player and they worked perfectly. Can anyone please tell me why my speakers dont work on my computer.
