Most newer Desktop computers these days come with the sound card or onboard sound card needed for you to hook up a 5.1, 6.1, 7.1 computer surround sound speaker system to your computer. A 5.1 surround sound speaker will make your games, movies, and music more realistic because you’ll have 5 speakers blasting out sound from the front, back, left and right direction. The sub woofer will also make low sounds like the rumble of an engine, helicopter, and drum sounds sound more realistic.
In most cases, for newer computers, you’ll just need to buy the 5.1 surround sound speaker system for your computer, and hook them up to the back of your computer like plugging in regular speakers. The plugs are color co-ordinated with the jacks on your speaker wires, so there is very little chance of plugging them in wrong. Even if you plug them in wrong, you can very easily pull out the plug and plug it into the right speaker jack.
For older computers, and cheaper laptops, you can get a USB 5.1 or better surround sound card which has all the audio jacks, and features needed for hooking up a surround sound computer speaker system on your computer or laptop with USB ports.
The advantage of using a USB sound card over a PCI sound card is the USB sound card can be used in multiple devices, and when you decide to change computers, or laptops. All you do is unplug the USB sound card, and plug it into another computer. The sound also might sound cleaner because there is less electrical interference outside of a computer then inside your computer.
You can also buy a PCI surround sound card to replace your onboard sound, or stereo sound card on your desktop computer if you prefer using PCI cards installed inside your computer instead of USB devives.
Watching movies, playing games, and listening to music on a computer with a surround sound speaker system is great because it sounds better then the inexpensive speakers which come with your computer, the speakers are affordable, and they don’t take up a lot of space compared to surround sound speakers made for HDTV, and home theater systems. There is also no complicated wiring when seting up surround sound speaker system since you just need to match the speaker plugs with the jack color, plug in your speakers, and it works.
