Have you ever tried playing an audio or video track and found that there was no sound at all? Though this could be attributed to a million different things, there are some cases when you cannot even drag the volume slider up and down because it is disabled.
In these cases, you can confirm that either the driver for the sound card is malfunctioning or it is improperly installed and sometimes, it can also be uninstalled. If you want to check to see if that’s the problem, you can go to Control Panel on your computer and click on System -> Hardware and select Device Manager.
In case your sound card doesn’t have the specific drivers installed, you should see a small yellow box with an exclamation symbol in it. You’ll need to reinstall the sound drivers to rectify this problem.
Again, knowing operating systems, there are different reasons why this could occur. Either you have recently installed a driver pack for Windows without checking for compatibility with your sound card or you have upgraded your operating system to a different service pack.
The most common transition would be from Windows XP Service Pack-2 to the next version. In these cases, the older drivers are not compatible with the newer version of the operating system. In some cases, the sound card and associated drivers may be so old that it is impossible to find drivers for latest operating systems. You might consider going down to a more compatible operating system or upgrading your sound card.
Driver interoperability is another phenomenon that can be discussed here. Sometimes, it may so happen that the hardware structure and the command engines of two components from the same manufacturer may be the same.
In these situations, one component’s driver could be used for the other to deliver a mediocre performance. Sometimes, the computer installs the wrong driver for a component due to user intervention which creates problems with the hardware performance. On rare occasions, the sound drivers could also be corrupt in which case you’ll have to download the latest drivers from the manufacturer’s website.
