I've never had to do it. I'd imagine the risk of damaging the PC via the sound card jacks are pretty slim.
Its depends on the output power of the device your connecting to.
Most computer speakers with subwoofer have the power going directly to it, so it is needed to get an extension for all the other speakers.
No most home speakers are supposed to be powered through an amplifier. A computer will not supply enough power to effectively run those speakers. Plus the wiring for computer and home speakers are very different.
There are many cables and components to a computer. The main cables for connecting the computer would be the power cable, and an Ethernet cable for connecting a non wireless PC to the internet.
the computer BIOS is set to power on when AC power is back. This can be turned off.
You need to plug the speakers into a sound output plug on your computer; often, the speakers will also require a separate connection to a power source.
Try some troubleshooting such as: 1) Make sure the speaker volume is turned up on the speakers if they have an audio knob on the speakers. 2) Make sure the speaker volume on the Task Bar is turned up and not muted. 3) If they are external speakers attached to the computer, make sure the power is on. 4) Make sure the cables connecting the speakers to the computer are attached. 5) Download the latest audio drivers from the maker of the speakers. 6) If you are playing a game, check in the game options to see that sound is enabled. That's all I can think of atm, good luck.
No. Some computer speakers require AC adapters, while others can run simply on battery power or USB.
USB computer speakers vary in sound quality. It all depends on the amount of available power as well as the sensitivity of your driver cones.
The TV will need to have AUDIO OUTPUT jacks to connect to the speakers or a amplifier to power the speakers and subwoofer.
Installing new speakers on a desktop computer is a very simple procedure. First, you must connect the speakers and the computer via usb cable that came with the computer. The best place to connect this perhaps is on the back of the computer. Then, plus in the 3.5 mm jack on the computer. Plug the power chord, turn the speakers on, and your all set!
While the clarity and power of computer speakers may vary, the one trait that separates soundsticks from speakers is their clarity and powerful abilities. Also the intentional design of the soundstick's satellite speakers offers a fuller, surround sound feel to an environment.
