Turn off the sound card on the PC


It's no secret that today no personal computer can do without a sound card. Now almost all motherboards contain an integrated sound card in their chipset. But the problem is that the integrated audio card does not have sufficient sound quality. Sometimes they also fail, for example, when a lightning bolt hits a PC. Therefore, advanced users prefer to use separate sound cards, when using them, the built-in audio card will need to be disabled.

Instruction manual

Insert a new sound card into the PCI slot on the motherboard. Naturally, you need to do this with a de-energized computer. Open the side cover of the case, then break the plug opposite the slot you need. After that, insert the card into the slot and fasten it with the screw. Close the system unit cover. Switch all the plugs from the old sound card to the new one, guided by the color of the plugs.

Turn on the computer and enter the BIOS. On most motherboards, for this you need to press the Delete key immediately after turning on the PC. The BIOS menu opens. The mouse does not work in it, use the arrows to move, to confirm Enter, to cancel the Escape (Esc) key. Find the “Integrated Peripherals” item in the menu, enter it by pressing Enter.

Next, find your sound card in the menu. Most likely, her name will be "AC97". Select this item and set it to “disable” with the arrow keys. Confirm the changes by pressing Enter. After that, exit the BIOS setup program, for this, press the F10 key and Enter. After that, the computer will restart, and the old sound card is disabled.

Disabling the sound card in BIOS

  1. To disable the sound card, you need to go into the BIOS. To do this, start the computer and, without waiting for the OS to boot, press a special key or a combination of both. Usually this is the “Delete”, “F1”, “F2”, “F11” or “Esc” button. When you turn on the computer, the system usually tells you which key to press to enter the BIOS (message type "Press *** to Enter Setup").
  2. After logging into the BIOS, find there the section that is responsible for configuring the embedded devices. The name of this item may vary, depending on the BIOS version: Advanced Features, Intergrated Peripherials or Chipset. Then you need to select the line “Onboard devices”.
  3. A list of embedded boards will be listed there. Find yours (this can be AC97, Realtek Audio, Audio, Onboard Sound, etc., depending on the type of sound card you have). Select this item and set it to Disable (Enable should initially be set).
  4. After making changes, exit the BIOS, without forgetting to save the settings. To do this, find something like "Exit and save." Usually in BIOS, this function is activated by pressing the "F10" key. Then the PC will reboot, during which the changes will be applied, that is, the sound card will be deactivated.

Sound card installation

The need for a new sound card may arise if the old one (built into the motherboard) burns out or you just don’t like the sound that it reproduces. To perform this procedure, your computer must have a PCI slot. However, on modern "motherboards" it may not be. Then it will be possible to purchase a card that is connected via USB. If you are not comfortable with a sound card on a laptop, then this solution will be useful for laptops.

How to install a PCI card

The installation process is simple, just be careful not to damage other components of the system unit and the wire. Procedure:

Traditionally, the motherboard has 4 connectors for sound cards (two PCI interfaces and two PCI Express x1 standards). One of the PCI ports will be closed by the cooling system, so there remains one where you need to make the connection.

  1. Turn off the computer (preferably remove all wires) and open the system unit. It is located behind the cover, which is mounted on small bolts.
  2. Remove the video card (often it interferes with the installation of the sound card), then it will need to be put back.
  3. Carefully insert a new card and attach it to the chassis using the special mounting screw.

Then you need to disable the built-in sound card, as described above.

How to find out the sound card model

You may need to find out what sound card is on your computer. For example, there was a power outage, and after that the sound from the computer disappeared. Reinstalling sound card drivers can help in this situation. Each model has its own drivers, so to find out which ones, you first need to look at the brand of the sound card manufacturer.

We learn through the device manager:

  • Click on the “Start” icon (it is located on the desktop bottom left),
  • Click on the inscription “My computer” and right-click,
  • In the menu that opens, click "Properties",
  • The "System Properties" window will appear, go to the "Hardware" section, then - "Device Manager",
  • You will see a list of all devices connected to your computer. Find the line “Sound, video and gaming devices”. At the very top, the name of the sound card installed on the PC will be indicated.

If you need to know more data:

  • Right-click on the device,
  • A context menu will appear, select the line “Properties” in it,
  • Go to the "Details" tab and find the "Property" section,
  • There, select "Equipment ID",
  • Here you will see many different values, click on the last line in the list and click "Copy",
  • Then in the search engine, paste this value,
  • Next, go to the search results, on the sites you can find the right driver.

  1. You can solve the problem in another way: using special utilities, such as Everest or SISandra. By launching one of these applications, you will find all the necessary data about your sound card. In addition, in these useful programs you can see the most detailed information in general about any component installed on your PC.
  2. If DirectX is installed on your device, you can also use its resources. The fact is that as part of this program there is an addition Direct Diagni. Having opened it, in the “Sound” section you will find the name of your sound card.
  3. Another option - no less reliable, but not too convenient - is just to remove the cover of the system unit (after disconnecting the PC from the network). On the sound card, like all other components, the mark should be indicated. There you can see the manufacturer of the video card, RAM blocks, processor, and so on. This is often more convenient than finding similar data in digital format.

After downloading the drivers and then installing them, restart the computer and check the sound. Now it should be.

Disabling the built-in sound card is a necessary procedure if you installed a discrete card and do not plan to use the old one anymore. Disabling via BIOS is the most effective way to do this, and everyone can perform this operation.

Disabling the integrated sound card in BIOS / UEFI

The ability to completely disable the sound card should start a search in the BIOS / UEFI, which is simply located in the settings of your motherboard. The integrated sound card belongs to the motherboard, and these will be its options that allow you to enable or disable the built-in music system. The first step is to enter BIOS / UEFI - you can do this in two ways.

  • Enter BIOS / UEFI from Windows 10

If you have Windows 10, you can do this quite simply. To do this, open the Start menu, then click the power icon to extract options for turning off the computer or restarting. Press and hold the key. shift on the keyboard, then press the button Reboot holding the key all the time shift.

After some time, advanced computer startup options will appear. Choose in turn "Solve problems> Advanced options> UEFI firmware settings." After clicking this option, the computer will reboot and automatically switch to the settings of the motherboard.

  • Enter BIOS / UEFI at computer startup

As an alternative to BIOS / UEFI, you can enter it at startup. On the initial screen, before the Windows logo (or another one that you are using) appears, information about which button should be pressed to enter the settings (SETUP). Usually it is the F12, F10 or DEL button (for example, “Press DEL to enter SETUP”). Press the appropriate button at computer startup to enter BIOS / UEFI.

  • Turn off the sound card in the BIOS

When you're in BIOS / UEFI, it's time to find options related to the integrated sound card. Manufacturers offer different panels for managing settings, but usually you should look for this option in the advanced settings of integrated devices.

Type option search Integrated Peripherals - here you will find settings that enable or disable any devices built into the motherboard, such as sound cards, graphics cards or network cards.

Sound card must be under name type Integrated Audio or HD Audio Controller. By default, this option will certainly be set to "On", which means the card is on. All you have to do is switch it to position Disabled and the built-in sound card will be deactivated.

Remember to exit BIOS / UEFI so that all changes are saved. Go to the main screen and search for the “Save Settings and Reboot” options.

Method 1: AWARD BIOS

If Phoenix-AWARD firmware is installed on your computer, we’ll refresh our knowledge of the English language a bit and begin to act.

  1. We reboot the PC and press the BIOS call key on the keyboard. In the AWARD version, this is most often Deloptions are possible from F2 before F10 other. Often a tooltip appears at the bottom of the monitor screen. You can see the necessary information in the description of the motherboard or on the manufacturer's website.
  2. Using the arrow keys, move to the line Integrated Peripherals and click Enter to enter the section.

We save the settings and exit the BIOS by clicking F10 or by selecting “Save & Exit Setup”.

  • Mission accomplished. The built-in sound card is disabled.
  • Method 2: AMI BIOS

    There are also BIOS versions from American Megatrends Incorporated. In principle, the appearance of AMI is not very different from AWARD. But just in case, consider this option.

    1. We enter the BIOS. In AMI, the keys are most often used for this. F2 or F10. Other options are possible.
    2. In the upper BIOS menu, use the arrows to go to the tab "Advanced".

    Here you need to find the parameter OnBoard Devices Configuration and enter it by clicking Enter.

    On the integrated devices page we find the line “OnBoard Audio Controller” or “OnBoard AC97 Audio”. Change the state of the sound controller to "Disable".

    Now move to the tab "Exit" and choose Exit & Save Changes, that is, exit from BIOS with saving the changes made. You can use the key F10.

    Method 3: UEFI BIOS

    Most modern PCs have an advanced version of BIOS - UEFI. It has a more convenient interface, mouse support, sometimes there is even a Russian language. Let's see how to disable the integrated audio card here.

      We enter the BIOS using the service keys. More often Delete or F8. We get to the main page of the utility and select "Advanced Mode".

    Confirm the transition to advanced settings with OK.

    On the next page we move to the tab "Advanced" and select the section OnBoard Devices Configuration.

    Now we are interested in the parameter “HD Azalia Configuration”. It can be called simply “HD Audio Configuration”.

    In the settings for audio devices, change the state “HD Audio Device” on "Disable".

    The built-in sound card is disabled. It remains to save the settings and exit the UEFI BIOS. To do this, click "Exit"choose “Save Changes & Reset”.

    In the window that opens, we successfully complete our actions. The computer restarts.

    As we can see, turning off the integrated sound device in BIOS is not at all difficult. But I want to note that in different versions from different manufacturers, the parameter names may slightly differ with the preservation of the general meaning. With a logical approach, this feature of “embedded” microprograms will not complicate the solution of the posed problem. Just be careful.
