How to Troubleshoot Computer Sound Problems

When a computer has no sound, the sound card may need to be replaced.

When sound problems strike, it can sometimes be difficult to know where to start on your quest to solve them. By following a measured troubleshooting plan that tests for simple solutions before moving on to more complicated and expensive fixes, you can figure out your sound problem more quickly and efficiently. Troubleshooting a computer requires that you check for the most mundane solution every time, even if you are usually too knowledgeable about computers to make absent-minded mistakes.

Things You'll Need

• Sound card driver
• Spare speakers
• External sound card (optional)

Instructions

1. Check the volume levels to make sure nothing is on mute and that the volume is on at a level you can hear. Volume controls to check include your computer volume control, the volume control on the software program you are using, and the volume control on the speakers playing the sound.

2. Try playing a sound from a different program.

3. Check your power sources. Ensure that all speakers and external sound devices are plugged in and powered on.

4. Check to see whether your sound card is enabled and functioning properly. This can be done in the hardware preferences section of your operating system, usually in the section pertaining to sound devices. From the sound hardware menu, you can see whether a device is functioning and turned on.

5. Restart your computer.

6. Find a new set of speakers and replace the ones you are currently using. Try again to play a sound.

7. From the sound hardware settings section you checked earlier, uninstall your sound card. To uninstall a sound card, you often right-click the sound card from the sound hardware menu and select "Uninstall." Restart your computer and allow it to re-detect and re-install the sound card.

8. Download a new driver software package from the sound card manufacturer and install it. If this does not work, consider replacing the sound card.

Tips & Warnings

• If you have an external sound card, you can plug it in to the computer to test whether the installed sound card is malfunctioning.
