No. As its own instructions probably point out, it accepts Line Level (pre-out) signals in the pattern of L/R; Sur L/Sur R; Center/Sub; which is typical of most PC soundcards that support 5.1 audio to powered speakers or other hi-fi.
Simple one - uninstall sound driver - reinstall. Typical one - Google your sound driver find that is there any updated one for windows 7?. Download and install. It will work. Sometime (very silly) connecting ur device properly also work. Thanks
The last point is the most important -- the speaker light is not glowing. That means it's not getting power, and nothing else is going to work.
If you have access to a multimeter (voltmeter) you can test the adaptor to see if it's producing the power that is on the label. That would help you figure out if the problem is the adaptor or inside the speaker.
If you bought it retail, I'd suggest taking it back. I can't say for sure where the defect is, but "I plug it in and it doesn't turn on" is a sure-fire indicaor that it's defective.
Go insto your speaker properties/configuration from the little speaker icon in your taskbar. Check to make sure you have it configures in a 5.1 format rather than stereo. If it is set in stereo change to 5.1 & hit the test icon. All speakers should now be working. Hope this helps.
Go to Control Panel >> Sounds and Audio Devices. Click on Advanced button under Speaker Settings and for Speaker Setup select 5.1 surround sound speakers from the options. Click Apply >> Ok and then check.
