External Sound Card



External Sound Card

Sound cards are usually internal devices that plug into peripheral component interconnect, or PCI, slots. Computers have limited internal space and a predetermined amount of PCI slots. A user can still upgrade a sound card even if there is no space left inside the computer case by using an external sound card. External sound cards may operate slower than internal cards because they are physically located further from the CPU, but this change in speed may not be noticed by average users.

How to Install an External Sound Card

1. Read your computer's documentation to find out if the computer's current sound card must be disabled before installing a new one. If so then you must disable the sound card before installing the External
Sound Card.

2. Consult the sound card documentation. The sound card may have a disk to install drivers. The documentation will explain if the drivers should be installed before or after the card is installed. Many external hard drives are plug and play
USB devices, which means your computer will automatically recognize the device as soon as it is connected and powered and may not require any separate drivers to be installed.

3. Plug the sound card in. External sound cards are typically not externally powered. USB devices which require external power should be powered before connecting to the computer via the USB port.

4. Install applications for the device. You may not need to install drivers because the computer's operating system should automatically install drivers unless they were installed in a previous step; however, sound cards are often bundled with software pages including programs such as sound editors, media players or audio optimization software.
