In most of the cases, it has been seen that whenever users are upgrading their computer’s operating system to Windows 10, there is no sound in the system or Windows won’t boot . This no sound issue is incessantly found lately and many corresponding reasons are aligned in order to exactly conclude the cause of it, it cannot be fixed easily with safe mode. The most common cause for this problem is found to be the outdated audio driver or missing sound driver in the PC after the OS is upgraded to windows 10.

About Sound Card Driver: Usually, Windows operating systems apply a generic audio driver that allows computers to recognize the sound card component and make use of its basic functions.

Audio problems with your Dell computer. Are you having sound problems on your Dell computer (such as bad sound quality or no sound at all). This article will show you how to update or fix your Dell Audio Driver. Sound problems are often related to Audio Drivers but this is not always the case. Adjust your computer’s audio output in your system settings, and your Teams audio output in your device settings in Teams. On a Mac, you will need to install a driver the first time you include computer audio in a Teams meeting. Just follow the simple wizard and click Install or Update. It takes about 10 seconds for the installation to complete.

Thus the only way to resolve this issue is to re-install the audio driver with the correct version which is compatible for the current Windows OS. The methods mentioned here articulate two basic ways which are discussed thoroughly in the article below:

  • To check speaker settings
  • To uninstall and re-install Audio drivers
Sound Laptops & Desktops Driver

Method #1: To Check Speaker Settings on Windows 10

In this method, firstly the speaker settings are checked thoroughly to ensure if the speakers are functioning properly prior to re-installing the audio driver. Sometimes, the issue might arise due to dysfunctional behavior of the speaker system thus re-installing the audio driver wouldn’t do any good in resolving the issue.

Step 1.From the home screen, right-click on the sound icon at the bottom right corner of the screen and select “Playback device” from the context menu.

Step 2.Once the playback operating interface turns up, make sure that there is a green tick next to the “speakers” category. It denotes that the speakers used are the default playback device.

In case the green tick is NOT there, the problem is definitely due to the speakers. On such occasion, click on the “speakers” option and click “Set as default” button underneath the category list to make it default playback device.

Step 3.Move to the advanced tab, and from the “Default Format”, choose a different bit depth and sample rate. Click on “Test” to check if the sound is coming. Keep repeating the process till you stumble upon the right format that works. Once you have found it, click “Ok”.

If you are unable to find a right format, prefer the method 2 to ensure rightful rectification.

Method #2: Uninstall and Re-install Audio Drivers on Windows 10

Once you are done with checking the speaker’s settings, you better be ready to uninstall the audio driver and to re-install it with the correct version compatible for the newly upgraded OS (Windows 10).

Step 1.From your keyboard, press the “Windows logo key + X” to prompt the quick-access menu.

Step 2.From the list of options in the menu, select “Device Manager” to open Device Manager.

NOTE: You can also open Device Manager by typing “devmgmt.msc” in the “Run” command.

Step 3.In the device manager interface, click on “Sound, video and game controllers” category to expand it. Right-click on the audio driver your system is currently using (For instance, Realtek High Definition Audio) and select “Uninstall” from the context menu.

Step 4. In case you are asked to confirm the uninstall process, check the “Delete the driver software for the device” box and then click “Ok”.

Step 5. Once you are done with this, reboot your computer to make the change permanent, and to check if the no sound issue is resolved or not.

Step 6. If the problem is not resolved which is quite obvious and mostly happens, you have to update your audio driver.

Now the audio driver can be updated in two further ways:

  • Manually
  • Automatic Driver Update

Manually: In this method, you have to manually find the correct version of the audio driver online and then download it and install it to resolve the issue.

Automatic Driver Update: In this method, you need not worry about which version to choose as the correct one as you can mistakenly download the incorrect version sometimes. A third party utility which is freely available on internet, called Driver Easy, would do the job for you. The steps are given as follows:

Step 1.Download the Driver Easy utility from online and install it correctly on your PC.

Step 2.Click “Scan Now” to initiate the scanning process, which would detect the missing or backdated audio drivers.

Step 3.Click on “Update” button next to the dysfunctional driver or you can click “Update all” to re-install afresh all the system drivers after the OS upgrade, which is much safer.

If you have done all the steps mentioned above accurately, the problem of no sound in your PC is ought to get solved.


No sound issue can give rise to several difficulties for instance, while working, notifications of mail or chat on social messengers would not possibly be apprehended by the user which at its worst can degrade the work rate and would lead to poor performance and even fatal disasters in case of emergency mails or chats. Not only that the user would not be able to watch videos or listen to any songs on his/her system which sounds quite boring. Thus, this article would definitely help the user to resolve the issue even if he is a novice with computers.

In Windows 10 you can write a universal audio driver that will work across many types of hardware. This topics discusses the benefits of this approach as well as the differences between different platforms. In addition to the Universal Windows drivers for audio, Windows continues to support previous audio driver technologies, such as WDM.

Getting Started with Universal Windows drivers for Audio

IHVs can develop a Universal Windows driver that works on all devices (desktops, laptops, tablets, phones). This can reduces development time and cost for initial development and later code maintenance.

These tools are available to develop Universal Windows driver support:

  • Visual Studio 2015 Support: There is a driver setting to set “Target Platform” equal to “Universal”. For more information about setting up the driver development environment, see Getting Started with Universal Windows Drivers.

  • APIValidator Tool: You can use the ApiValidator.exe tool to verify that the APIs that your driver calls are valid for a Universal Windows driver. This tool is part of the Windows Driver Kit (WDK) for Windows 10, and runs automatically if you are using Visual Studio 2015 . For more information, see Validating Universal Windows Drivers.

  • Updated DDI reference documentation: The DDI reference documentation is being updated to indicate which DDIs are supported by Universal Windows drivers. For more information, see Audio Devices Reference.

Create a Universal Audio Driver

For step-by-step guidance, see Getting Started with Universal Windows Drivers. Here is a summary of the steps:

  1. Load the universal audio sysvad sample to use as starting point for your universal audio driver. Alternatively, start with the empty WDM driver template and add in code from the universal sysvad sample as needed for your audio driver.

  2. In the project properties, set Target Platform to 'Universal'.

  3. Create an installation package: If your target is device running Windows 10 for desktop editions (Home, Pro, Enterprise, and Education), use a configurable INF file. If your target is device running Windows 10 Mobile, use PkgGen to generate an .spkg file.

  4. Build, install, deploy, and debug the driver for Windows 10 for desktop editions or Windows 10 Mobile.

Sample Code

Sysvad and SwapAPO have been converted to be Universal Windows driver samples. For more information, see Sample Audio Drivers.

Available Programming Interfaces for Universal Windows drivers for Audio

Starting with Windows 10, the driver programming interfaces are part of OneCoreUAP-based editions of Windows. By using that common set, you can write a Universal Windows driver. Those drivers will run on both Windows 10 for desktop editions and Windows 10 Mobile, and other Windows 10 versions.

The following DDIs to are available when working with universal audio drivers.

Convert an Existing Audio Driver to a Universal Windows driver

Follow this process to convert an existing audio driver to a Universal Windows driver.

  1. Determine whether your existing driver calls will run on OneCoreUAP Windows. Check the requirements section of the reference pages. For more information see Audio Devices Reference.

  2. Recompile your driver as a Universal Windows driver. In the project properties, set Target Platform to 'Universal'.

  3. Use the ApiValidator.exe tool to verify that the DDIs that your driver calls are valid for a Universal Windows driver. This tool is part of the Windows Driver Kit (WDK) for Windows 10, and runs automatically if you are using Visual Studio 2015. For more information, see Validating Universal Windows Drivers.

  4. If the driver calls interfaces that are not part of OneCoreUAP, compiler displays errors.

  5. Replace those calls with alternate calls, or create a code workaround, or write a new driver.

Creating a componentized audio driver installation


To create a smoother and more reliable install experience and to better support component servicing, divide the driver installation process into the following components.

  • DSP (if present) and Codec
  • APO
  • OEM Customizations

Optionally, separate INF files can be used for the DSP and Codec.

This diagram summarizes a componentized audio installation.

A separate extension INF file is used to customize each base driver component for a particular system. Customizations include tuning parameters and other system-specific settings. For more information, seeUsing an Extension INF File.

An extension INF file must be a universal INF file. For more information, see Using a Universal INF File.

For information about adding software using INF files, see Using a Component INF File.

Submitting componentized INF files

APO INF packages must be submitted to the Partner Center separately from the base driver package. For more information about creating packages, see Windows HLK Getting Started.

SYSVAD componentized INF files

To see an example of componentized INF files examine the sysvad/TabletAudioSample, on Github.

File nameDescription
ComponentizedAudioSample.infThe base componentized sample audio INF file.
ComponentizedAudioSampleExtension.infThe extension driver for the sysvad base with additional OEM customizations.
ComponentizedApoSample.infAn APO sample extension INF file.

The traditional INF files continue to be available in the SYSVAD sample.

File nameDescription
tabletaudiosample.infA desktop monolitic INF file that contains all of the information needed to install the driver.

APO vendor specific tuning parameters and feature configuration

Sound Laptops & Desktops Drivers

All APO vendor system specific settings, parameters, and tuning values must be installed via an extension INF package. In many cases, this can be performed in a simple manner with the INF AddReg directive. In more complex cases, a tuning file can be used.

Base driver packages must not depend on these customizations in order to function (although of course functionality may be reduced).

UWP Audio Settings APPs

To implement an end user UI, use a Hardware Support App (HSA) for a Windows Universal Audio driver. For more information, see Hardware Support App (HSA): Steps for Driver Developers.

Programmatically launching UWP Hardware Support Apps

To programmatically launch a UWP Hardware Support App, based on a driver event (for example, when a new audio device is connected), use the Windows Shell APIs. The Windows 10 Shell APIs support a method for launching UWP UI based on resource activation, or directly via IApplicationActivationManager. You can find more details on automated launching for UWP applications in Automate launching Windows 10 UWP apps.

APO and device driver vendor use of the AudioModules API

The Audio Modules API/DDI is designed to standardize the communication transport (but not the protocol) for commands passed between a UWP application or user-mode service to a kernel driver module or DSP processing block. Audio Modules requires a driver implementing the correct DDI to support module enumeration and communication. The commands are passed as binary and interpretation/definition is left up to the creator.


Audio Modules is not currently designed to facilitate direct communication between a UWP app and a SW APO running in the audio engine.

For more information about audio modules, see Implementing Audio Module Communication and Configure and query audio device modules.

APO HWID strings construction

APO Hardware IDs incorporate both standard information and vendor-defined strings.

They are constructed as follows:


  • v(4) is the 4-character identifier for the APO device vendor. This will be managed by Microsoft.
  • a(4) is the 4-character identifier for the APO, defined by the APO vendor.
  • n(4) is the 4-character PCI SIG-assigned identifier for the vendor of the subsystem for the parent device. This is typically the OEM identifier.
  • s(4) is the 4-character vendor-defined subsystem identifier for the parent device. This is typically the OEM product identifier.

Plug and Play INF version and date evaluation for driver update

The Windows Plug and Play system evaluates the date and the driver version to determine which drive to install when multiple drivers exist. For more information, see How Windows Ranks Drivers.

To allow the latest driver to be used, be sure and update the date and version, for each new version of the driver.

APO driver registry key


For third party-defined audio driver/APO registry keys, use HKR with the exception of HKLMSystemCurrentControlSet.

Use a Windows Service to facilitate UWP <-> APO communication

Dell Desktop Sound Driver

A Windows Service is not strictly required for management of user-mode components like APOs, however, if your design includes an RPC server to facilitate UWP <-> APO communication, we recommend implementing that functionality in a Windows Service that then controls the APO running in the audio engine.

Building the Sysvad Universal Audio Sample for Windows 10 Desktop

Complete the following steps to build the sysvad sample for Windows 10 desktop.
