Hi I would check the plug to see if the wires have come loose or the fuse is gone in the plug this can happen at any time and its the last place you always look, the plug looks fine but

Hi names Rui i like to help you by giving you step by step instruction in propely hocking up your logitech speakers:

Instructions

1. Connect the black plug of the rear right speaker into the black plug on the subwoofer.

2. Connect the yellow plug on the rear left speaker into the yellow input on the subwoofer.

3. Connect the red plug of the front center speaker into the red input on the subwoofer.

4. Connect the white plug of the front left speaker into the white input on the subwoofer.

5. Connect the d-sub connector plug from the front right speaker into the d-plug connector on the subwoofer.

6. Connect the green, black and orange input to the matching plugs on your computer. If you have a four-channel sound card, connect the green plug from the input audio cable to the front plug of the card and the black plug to the rear plug. Do not connect the orange input. If you are using a two-channel sound card, connect the green plug from the input audio cable to the "Line Out" jack on the sound card. Do not connect the green and orange plug.

7. Plug the subwoofer power chord into the electrical power outlet.

8. Place your subwoofer on ground around your computer desk. Position the front center speaker on top of your computer monitor.

9. Place the left and right front speakers on the sides of the monitor. Position the left and right rear speakers behind you, making sure they are pointing toward the front left and right speakers.

10. needs to support 5.1 surround. Normally, more than three sockets for sound indicates that it does. Then you need to use the software that comes with the sound hardware to configure it for 5.1 - Default will be 2.1 or just 2.
Check the control panel out. This is a lot easier under Windows 7.- Here you can access what you need via the speaker icon on the system tray (right click)
There is NO problem with your OS or hardware, this is pretty standard...

hope this will help you solve your problem.

try swapping the speakers around if the problem still persists either the speaker is faulty or
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
orbe sure to wear an anti static earth strap before touching anything inside your computer
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your sound card dust causes static to build up in a computer causing it to overheat any many other problems
hope this helps

which operating system do you use? and check the sound driver from { if windows,right click my computer then click manage then device manager, see there is sound driver is installed or not.} if not then install sound driver.

sounds like a corrupt driver. Go to device manager, and see if the USB tree has a yellow exclamation, if yes, uninstall USB driver and reboot.

verify if at rear is a button with 1 and 0 position
that must be on 1

Check whether the power plug of machine is good, connections, fuse, main wire, etc. All good, then try below:

Plug off the wall socket. Open up the machine. Remove, reseat and reconnect every connector at least 3 times. Remove the motor control board, spray it down with electronic cleaner along with all connections by disconnecting them, spraying them down. Disconnect and connect a few times to ensure good contact.. This normally works.

Pl give me a ‘very helpful’ rating for the free help, thanks.

If the power light on the speakers isn't on, then the power supply going to the speakers is either in a bad outlet (test the outlet with a voltage meter) or the plug isn't firmly seated. Best of luck in your new home and hope this solves your problem.

your speaker connections are plugged in incorrectly or the speakers are not plugged in and powered on.
check the back of the computer where your speakers are plugged in and make sure you speakers are plugged into the right colors

Your machine may not be receiving adequate voltage to start. Make sure your machine is plugged in. Also, check the circuit breaker panel to make sure all the circuit breakers are in the correct positions. Or check to make sure no fuses in the fuse panel are blown. Try plugging something else into the same outlet. If it won't work either, then there is likely something wrong with the power outlet. Any of these could be the reason power is not getting to your machine. Also, refrain from using an extension cord to plug your machine in.
