Question about Altec Lansing ADA 305 Computer Speakers
A few possibilities exist. I would first check all the connections, and wiggle all the connectors and plugs to see if any one of them is causing it including the power cable. Also try to play with the ON/OFF/Volume switch to see if that's intermittent. Second, for quick isolation of the problem I would connect them to another PC - did the clicking and flickering go away? If it did, then your PC's audio circuitry is causing it - possibilities: defective audio card, or Motherboard (MB) if it has integrated audio, bad connections on MB or audio card, if you're also using analog audio connections going from the back of your CD/DVD RW to the audio card/MB then remove those wires and see if that problem goes away - those wires are notorious for picking up all kinds of noise and feeding that noise to your audio controller. One other thing to try is to completely uninstall and reinstall the audio drivers or even try a different revision.

There are a few simple things to check first:
Make sure your computer has a sound card.
You must be logged on as an administrator to perform these steps.
Open Device Manager by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager.
If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Expand the Sound, video and game controllers category. If a sound card is listed, you have one installed. If no sound card is listed, You will need to install one. See Install or remove a sound card.
If there is a yellow question mark next to
the name of the sound card, there might be a problem. Right-click the
name of the sound card, and then click Properties.
Click the General tab, and then look in the Device status box to identify problems with the sound card.
Make sure your speakers are plugged into a working power source and turned on.
Make sure your speakers are correctly connected to the computer.
On your speakers, find the cable that plugs
into your computer. Make sure that the speaker cable is plugged into the
speakers and the correct jack on the computer. For example, if the
cable is a 1/8 inch cable, there should be a round jack for it on the
back of the computer. If it is a universal serial bus (USB) cable, it
will plug into any USB port on your computer.
Make sure that the speaker volume is not muted or turned down too low.
Open Volume Control by clicking the Start button , clicking Control Panel, clicking Hardware and Sound, and then, under Audio Devices and Sound, clicking Adjust system volume.
Under Main Volume, move the slider up or down to raise or lower the volume.
Some mobile PCs have an external volume
control on the outside of the case. If you're using a mobile PC, check
the external volume control.
Make sure your headphones are not plugged into
the line out (headphone) jack of your sound card or computer (unless
you want to be listening with headphones rather than speakers). When you
plug in headphones, most computers automatically cut the sound to the
