No Audio and Device Drivers

Does your computer have no sound, even though you just used your speakers to watch a video or listen to music recently, and you know the sound was working? Numerous issues could be causing the computer to stop producing sound suddenly and, most times, the problem is that one of the speaker or audio device drivers has a problem. That said, let’s look at who an audio driver works, some symptoms and causes of no sound, as well as how to fix the problem. However, before you can fix the problem, you must first understand what the audio device driver is, and how it works, as knowing this information it may be easier to diagnose and fix future problems.

How the Audio Device Works

A sound card, the device that allows the sound to work, connects to the computer using either integration or expansion slots; both work the same but are in different places. If the sound card is integrated, it means that it is part of the computer’s motherboard and cannot be removed. The motherboard is the “brains” of the computer. A sound card using an expansion slot can be removed, and is called a stand-alone card, which typically comes in the form of a PCI or PCIe card. 

The sound card is essentially a processor, or a chip that is tasked with sending all the audio signals to the proper places. For example, if you want to listen to music, the audio device tells the operating system to send the music file’s audio signals to the speakers. The same is true of most operating system sounds as well.

Because the sound card handles all the sound signals, the CPU is allowed to focus on more important tasks, making the computer run faster. Nevertheless, without compatible software, the sound card has no idea what to do, so the computer will not produce sound.

What a Device Driver and How Does it Work?

The driver is software that allows hardware to work properly. The audio driver is the software that tells the audio device where to send the signals. Essentially, a driver is an kind of instruction manual that the hardware can read. It contains everything the hardware needs to know including what type of hardware it is, what it is supposed to do, and where to send specific signals on the computer.

The problem with drivers is that they are “temperamental,” meaning that is they are even the slightest bit out of date, they may not work properly, causing the hardware to receive the wrong signals. In most cases, the reason that a computer has no sound is typically because the audio driver needs an updated version. 

Typically, the same manufacturer that makes the hardware develops the drivers to make sure the hardware will work properly because if the wrong driver is installed and used, the device might work, but it will not work perfectly. However, some types of hardware are also compatible with generic drivers; Microsoft makes a host of generic drivers that are compatible with all types of hardware, but generic drivers are typically older versions of the current version, making them unstable.

New software drivers are constantly being developed in the race to offer the best performance in the hardware by improving on the existing designs. This race for the drivers to perform better than the hardware is called “hardware acceleration,” and is also the reason that driver updates are always available and recommended to download and install as soon as possible after the update has been released. Some hardware use drivers that can be installed simply by clicking a button on the mouse, but in most cases, audio drivers, as well as other driver types, need to be installed manually, meaning the user has to know where to find the driver, how to download it, and where to install the software.

OK, so now you know what an audio device and audio driver are and how they work, we can finally look at why your computer has no sound and how we can possibly fix the problem.

What Causes Sound Problems?

We have established that your computer is not emitting any sound, even though it never had a problem before. While numerous problems could exist, the most common include wrong audio settings, damaged audio card, audio card driver is damaged, outdated, missing, or otherwise incompatible. Many times, an accidental change to the sound configurations or audio settings when updating the audio driver is the cause because they are updated to frequently. Additionally, the audio card itself can become damaged quite easily, especially when they are used frequently. Another common problem is that when the Microsoft Windows OS updates, it can make the drivers incompatible, thus stopping the card from producing sound.

Since these are the most common causes of the computer not having sound, let’s look at some ways to diagnose and fix each of these problems. If you would like to do this yourself, then our article on how to fix the “no sound” problem manually is a great place to start, since here we will cover the automatic processes to avoid the problems that come with manual diagnosis and troubleshooting. 

Fix Your “No Sound” Problems Easily and Automatically

As mentioned above, the usual reason that the sound will not work is because there is something wrong with the driver, which is called a driver conflict.  Because millions computer models are on the market, millions of driver types also exist, which makes it practically impossible to find the right driver without causing damage to your computer are wasting precious time. Not to worry, though, even the most skilled IT techs will use these steps to diagnose and fix these types of problems.  

The automated driver-finding tool is the best bet to find the right driver without causing problems. Not only will the automated driver finder tool help save time, but it will also make sure that a compatible driver is installed the first time, thus making the process safer.

Using DriverUpdate, the user is assured that the driver installed is the right one. This tool not only detects what the problem with the driver is, but it also detects exactly which driver and driver version your computer needs so the hardware can to work right. DriverUpdate practically guarantees that only the most up-to-date drivers are installed, so that there is no chance of damaging your sound card or computer system with unintentional bad driver downloads. Knowing that DriverUpdate will install the proper drivers no matter what makes problems with lack of computer sound practically disappear, and will make the need to manually install the drivers something you never need to worry about again.
