Tech Question of the Week

Latesha Rhoden: The Internet contributes to the flow of information and the effective sharing of lessons, but it also exploits information that could be easily taught and passed down through generations. There is a breakdown in the lines of communication between generations because individuals rely greatly on the acquisition of information through the Internet and online encyclopedias. So even though the Internet does strengthen the knowledge or the transfer of knowledge, it also results in possible miscommunication.

Tech Problem of the Week

No sound coming from computer speakers

Why you need to know

Occasionally, plugging in a headphone or external sound device into a computer may interfere with the internal sound settings or memory. This is evident when you see a presenter's lips moving on video or media-player applications continue working, but no sound is delivered from the speakers, even when the volume is adjusted. As soon as the headphone or external speakers are plugged in, it begins to work again. In some instances, the sound does not return. This could mean the software drivers have been corrupted or require an update or the sound card is damaged, loose or needs a driver update.

What you will need

The computer

Internet connection

External speaker or headphone service

What to do

1 Restart the computer before attempting to check the driver settings. Allow the computer to load settings then open the media-player application and see if sound has returned.

2 If sound has returned, it could mean the computer 'forgot' the settings due to the continuous insertion and removal of the external cable for the headphone or speaker device. Nevertheless, still check for possible driver updates.

3 Go to 'Control Panel' and click the 'Systems' icon access 'Device Manager'.

4 In 'Systems' of a Windows 7 PC you will see 'Hardware' under which you find 'Device Manager', but Windows 8 PCs will take you directly to the manager tab.

5 In 'Device Manager' all hardware is listed. Select the arrow or '+' beside the 'Sound, Video and Game controllers' to see the sound or USB devices plugged into the computer.

6 Normally, 'High Definition Audio Device' is under the 'Sound, video and game controllers' options. Double-click on 'High Definition Audio Device' to see the status i.e. working or not working properly.

7 Other options include 'Driver', 'Details' from product description to security, and 'Events' that show the previous updates or product installation information. The 'Driver' tab will show any available updates and explain the download process. But ensure that you have the computer model number as well as the audio device information to carry out the necessary updates.

8 After the driver or sound card update is installed, restart the computer. The speakers should be working properly now.
