Muting Windows 10 Sound

Hardware acceleration of graphics and sound is an increase in the speed of their processing due to the transfer of control of playback processes from the central processor directly to the video adapter or sound card, due to which the tasks of processing graphics and sound are transferred to these devices. This reduces the load on the processor, and increases performance. Hardware acceleration in Windows 10 is enabled by default. In some cases, enabled hardware acceleration can cause problems with playing video and sound in games and videos. If you are sure that the source of the problem is not the driver of the video adapter or sound card, then there is a need to disable hardware acceleration.

What is hardware acceleration in Windows 10, how to enable and disable

Hardware acceleration of video graphics and sound in Windows 10 significantly improves the performance of your computer when working with multimedia applications and user games. This is due to the fact that the direct processing of commands used in media functions is transmitted directly to video graphics and sound adapters. The central processor is freed from unnecessary work, which significantly accelerates parallel processes. In this regard, many users have questions about how to enable hardware acceleration. At the same time, graphics and sound may not work correctly when hardware acceleration is enabled. This requires disabling it.

Incorrect operation of applications can occur when installing the wrong video card driver. Braking may occur during the game, the image on the monitor will move in jerks. This happens if the application cannot access hardware acceleration. Directx. In this case, you need to find and install the driver that is most suitable for the adapter.

In Windos 10, hardware acceleration is enabled by default. This can be easily verified by opening the tab “Control Panel”. “Screen” —- “Advanced Screen Settings” —- “Graphic Adapter Properties”. In the properties, the Diagnostics tab, designed to enable hardware acceleration, is missing. Let’s see how to turn off and turn on hardware acceleration in Windows 10.

Graphics settings

1. Disable hardware acceleration and enable it again through the Windows 10 registry

Right-click the Start button. Select "Run." Enter the regedit command.

We pass to the branch [HKEY_CURRENT_USER \ Software \ Microsoft \ Avalon.Graphics] "DisableHWAcceleration" = dword: 00000001 (1). In this position, hardware acceleration is enabled.

To turn off hardware acceleration, change 1 to 0. Hardware acceleration is turned off. [HKEY_CURRENT_USER \ Software \ Microsoft \ Avalon.Graphics] "DisableHWAcceleration" = dword: 00000001 (0).

To enable hardware acceleration again, change 0 to 1.

2. You can use the DirectX Control Panel from the DirectX SDK utility. Download the utility from the Microsoft website: Select the DirectDraw tab. Check the box next to Use Hardware Acceleration. Hardware graphics acceleration enabled. Accordingly, unchecking, disable hardware acceleration.

Prevent browser acceleration

If you have problems viewing the video directly in the browser, you can turn off hardware acceleration in its settings.

We show this using the example of the Rambler-Browser. In other browsers, the same principle of disabling.

In the Settings we find the System section, uncheck the Use hardware acceleration (if available) box, as shown in the picture.

You can disable hardware acceleration in the settings of Adobe Flash Player. Right-click on the video image and uncheck the Display tab, thereby disabling hardware acceleration.

Sound setting

Like video graphics, hardware-based sound acceleration is enabled by default in Windows 10. Any malfunctions with sound during the operation of the applications indicate that, most likely, the improper sound driver is installed. If, after installing the appropriate driver, the problem with sound does not disappear, then you can try disabling hardware sound acceleration.

Enable and disable

Download the DirectX SDK utility from the Microsoft website. Select the Audio tab. Move the “Direct Sound Debug Level” slider to the far left. Hardware sound acceleration is disabled. Accordingly, in the right extreme position of the slider, hardware acceleration of sound is turned on.

How is the level determined?

The hardware sound acceleration level is determined by the position of the “Direct Sound Debug Level” slider. In the Less position, acceleration is off, in the acceleration position is on. When the slider is in the middle, the level of hardware sound acceleration is 50%.

Since Windows 10 implements an algorithm to enable hardware acceleration by default during installation, as a rule, it is only necessary to disable it. This can be done through the registry, through third-party utilities or in a browser. This need arises extremely rarely. Errors are usually associated with incorrect user actions. Therefore, the main recommendation is to carefully act when installing the operating system and third-party programs.
