Make sure that your computer
and speakers are plugged in, have power and are turned on. If the

Retest the sound. If you still
don't have any sound, make sure the cable connecting the speakers to the
computer (known as a 1/8-inch TRS cable) is plugged into the green

If everything is grayed out, you

Windows will automatically detect and install your audio device upon
