Audio problems are nothing new for computers. There are various reasons why no audio would be present either through the PC speaker or through external speakers. The best thing about the issue though is that the causes are never usually hard to fix. Detecting the cause is what takes the most time. Nonetheless, the end result is that the problem is fixed and audio is restored to the computer. Let us consider a few possibilities as to why audio would not be present and how to fix it.

One of the times when audio disappears from the computer is when the sound card fails. At this point you will need to change the card. Sound card failure can happen for a number of reasons. In any case, a new one will have to be bought. Then there are times when the sound card is fine but the sound drivers get corrupted. A re-installation of the drivers should solve the problem. Thirdly, some people lose audio after installing a piece of hardware or even software. Even upgrading your Windows OS can result in sound loss. This occurs because drivers get mixed up or even deleted accidentally during the installation or upgrade process. If trying to re-install the drivers does not solve the problem, you may have to do a roll back using System Restore.

If there are more serious issues as to why you have lost audio on your computer, you can consult Microsoft’s website for Windows OS or Apple’s website for the MAC OS. In addition, there forums that you can search for on the internet that may be able to help you.
