How to install a computer sound card

Buying tips and help

Tip: Most computers and motherboards today have a sound card on-board, which means you may not need to install a sound card.

Before getting started

  1. Write down important information from the top or bottom of the card such as the model number, serial number, and specifications.
  2. Ensure you are familiar with ESD and its potential dangers.
  3. When physically installing the sound card, ensure the computer is off.

Set Jumpers

While today most sound cards are configured through Plug-and-Play or through software configuration, if your sound card has jumpers, verify that the jumpers are properly set. These jumpers are usually used to set the IRQ, IO, and DMA addresses.

We would recommend these settings be set to IRQ-5 I/O-1 DMA-220 (unless it conflicts with other peripherals currently installed in the computer).

For additional information about resource settings, see our resources page.

Install into Expansion slot

Today, sound cards are connected into the PCI slot. Locate an available expansion slot in the computer and gently push the card into the slot until it snaps and holds place. Once the card is in the slot, place a screw into the top of the card to hold the card into position.

Attach internal cables

Most sound cards have the availability of connecting a CD audio cable to the card itself. If present, connect the CD audio cable from the back of your CD-ROM to the sound card now.

Line out on the back of sound card

Place the case back onto the computer and connect the keyboard, monitor, power, and either a pair of headphones or speakers to the line out on the back of the sound card.

In the picture is an example of the back of a sound card. With most sound cards, the line out connection is the light green jack.

CMOS Setup

It is only necessary to enter CMOS setup if your computer has an on-board sound card. If present, the on-board sound card must be disabled before the new sound will work properly.

Software setup

Once the sound card has been physically installed into the computer, the sound card should have included software to install the sound card. Use this software to install the card into the computer.
