How Do Sound Cards Work?

What Are Sound Cards?

A sound card is a device that is installed inside of your PC to allow sound to be heard from it. Some computers have built-in sound cards, and some have sound cards that are plugged into your computer's USB port. The computer's motherboard has a sound card attached to it. Even though most computers are equipped with sound cards already installed, if you are not happy with its performance, you have the option to upgrade it. If you use your computer to listen to music or watch movies, you should consider purchasing a high-quality sound card. Sound cards are sold at reasonably fair prices.

How Do I Use a Sound Card?

When you purchase your sound card, it will come with a CD. This CD is used to install the sound card on your PC. Once you have inserted the sound card in your PC, you will need to install the software from the CD ROM. You will need to install the correct sound card driver that is designed for your PC. If you do not have the correct driver installed, you will not be able to hear sound from your PC. Most manufacturers provide the correct drivers on their website. Once you have installed the sound card and restarted your PC, Windows also automatically detects that there has been a hardware change and will give you the option to search for drivers to install.

What Are the Types of Sound Cards?

You have the option to choose a USB sound card or an internal sound card. If you decide to choose an internal card, you will have to open the case of your PC. The sound card is inserted in the expansion slot of your PC. If you are upgrading your sound card and your motherboard has one attached, you may disable it in your Windows control panel so that it does not conflict with your new sound card. A USB sound card is connected to your PC by inserting it into the USB port on your PC and installing the software from the accompanying disk. Most users prefer this type of sound because it is easier to install.
