Your system’s audio might not work after Windows update 2004 if the memory integrity of Windows Security is hindering the operation of the audio device. Moreover, corrupt, outdated, or incompatible audio drivers may also cause the error at hand.
The user encounters the issue, after the update when the system’s audio stops working properly (either mic, speaker, or both). The issue is reported on both i.e. built-in & external sound cards.
Before moving on with the solutions to fix no audio output, make sure your speakers/headphones are not muted and their jacks are properly inserted into the port (make sure front & back panels are enabled in the Audio Manager). Additionally, check if Ease of Access Audio Settings are properly configured (device volume and change the device or App volumes are set to 100% ). Furthermore, check if running the Audio Troubleshooters (Playing and Recording Audio) solves the issue. Also, make sure the audio output is not set to digital audio or 5.1 (set it to stereo) and your mic is set as the default communication device. Additionally, check if starting your system with bare minimums solves the issue.
Solution 1: Change Start Up Type of Windows Audio Service to Automatic
You may encounter the error under discussion if the start-up type of Windows Audio Service is not set to Automatic as it can create delays when called by processes. In this context, changing the start-up type of Windows Audio Service to Automatic may solve the problem.
- Open the Windows menu by pressing the Windows key and search for Services. Then, in the search results, right-click on Services and then choose Run as Administrator.
- Now, right-click on Windows Audio Service and select Properties.
- Then expand the dropdown of startup type & choose Automatic.
- Now click on the Apply/OK buttons and reboot your system. Upon reboot, check if the system’s audio is working fine.
- If not, open Windows Audio service properties (step 1 to 2). Now, navigate to the Logon tab and select the Local System Account.
- Then click on Apply/OK buttons & reboot your PC.
- Upon reboot, check if your system is clear of the audio error.
Solution 2: Disable the Audio Enhancements
Third-party vendors & Microsoft add enhancement packages to make your system’s sound perfect (called Audio Enhancements in Windows 10). But these enhancements can sometimes break the basic operation of the audio device and thus cause the error at hand. In this scenario, disabling the audio enhancements of your audio device may solve the problem.
- Right-click on the volume icon in your system’s tray and then choose Open Sound Settings.
- Now, click on the link of Sound Control Panel (under related settings) & then, in the playback window, right-click on your audio device (if you have more than one audio device, then right-click on any one of the devices).
- Then, in the menu shown, select Properties and navigate to the Enhancements tab.
- Now, check the option of Disable All Enhancements and click on the Apply/OK buttons.
- Then reboot your machine and upon reboot, check if the system audio is working fine.
- If not, and you have more than one audio device in the playback tab (step 2), then repeat the same process to disable audio enhancements of other devices & check if the system’s audio is working fine.
Solution 3: Add Services to Local Groups
You may encounter the error at hand if your local group user does not have access to the required system services. In this context, adding the services to the local group may solve the problem.
- Click on the Windows button to open the Windows menu and search for Command Prompt. Then, right-click on the Command Prompt, & in the menu shown, choose Run as Administrator.
- Now execute the following:
net localgroup Administrators /add networkservice net localgroup Administrators /add localservice
- Then exit the Command Prompt & reboot your machine.
- Upon reboot, check if the system’s audio is working fine.
Solution 4: Update/Reinstall the Audio Drivers
You may encounter the error under discussion if the audio drivers of your system are outdated, corrupt, or incompatible. In this case, reinstalling the audio drivers may solve the problem. But before updating the driver, you may try to roll back the driver or install an older audio driver to check if that resolves the issue.
- Update the system drivers (including the system’s BIOS) and Windows to the latest build. You can also check the Windows Update Catalog website or Intel Download Center for an updated version of drivers.
- After updating the system drivers, check if the system’s audio is working fine.
- If not, right-click on the Windows button and in the menu shown, choose Device Manager.
- Now, expand Sound, Video, and Game Controllers and then right-click on your audio device.
- Then select Uninstall Device and in the next window, check the option of Delete the Driver Software for This Device and click Uninstall. If you are using a sound manager (like Realtek Audio Manager), then uninstall it as well (it is better to run DDU) & remove its traces from the installation directory.
- Now, reboot your machine and upon reboot, check if the Audio issue is resolved (as Windows will install the default audio device driver).
If this doesn’t work, we will try to manually update the drivers and select the ones that are to be installed.
- Open the Device Manager (step 3) and expand Sound, Video, and Game Controllers.
- Now, right-click on the problematic audio device and choose Update Driver.
- Then select Browse My Computer for Drivers and choose Let Me Pick for a list of Available Drivers on My Computer.
- Now, select the default “High Definition Audio Device” and click on Next (ignore any warnings, if received). If the said option is not visible, uncheck the option of Show Compatible Hardware.
- Then follow the prompts on your screen to complete the driver installation process.
- Now, reboot your machine and upon reboot, check if the audio issue is resolved.
- If not, disable the onboard audio device in the system’s BIOS and then check if removing/reinstalling the audio driver resolves the issue.
Solution 5: Disable Memory Integrity in the Windows Security
Your system’s audio might not work if its driver is not compatible with the memory integrity of Window Security (which will stop the execution of the driver). In this scenario, disabling memory integrity in Windows Security may solve the problem.
- Launch the Cortana Search by pressing Windows + S keys and search for Windows Security. Now, select Windows Security.
- Now, open Device Security, and then, in the right pane of the window, click on Core Isolation Details (under Core Isolation).
- Then disable the option of Memory Integrity and reboot your system.
- Upon reboot, uninstall the audio drivers (as discussed in solution 4) and reboot your system
- Upon reboot, reinstall the latest OEM drivers (if Windows did not automatically install the drivers) and check if the system’s audio issue is resolved.
Solution 6: Reinstall Intel SST OED Driver
You may encounter the error under discussion if the Intel Smart Sound Technology (SST) OED driver is corrupt. In this context, reinstalling the Intel SST OED driver may solve the problem.
- Right-click on the Windows button to open the Quick Start Menu and select Device Manager.
- Now, expand System Devices and then right-click on Intel Smart Sound Technology OED (Intel SST).
- Then select Uninstall Device and check the option of Delete the Driver Software for This Device.
- Now click on Uninstall and then wait for the completion of the uninstallation of the driver. Repeat the same if there is an SST Audio Control Driver.
- Then check for Windows updates (a new Intel Corporation System driver will be installed) or install the OEM driver and then check if the system is clear of the audio issue.
If the issue persists, then reinstalling the Dolby access driver (driver from the OEM site and application through the Microsoft Store) solves the issue. If not, then disabling/enabling Plugin Alliance plugins solves the issue. If you are using Sound Blaster Command, you may have to set the playback to Direct Mode. Furthermore, check if setting the playback device to SPDIF – Out (if you are using a SPDIF cable) solves the issue. If the issue is still there, then you may have to remove the Windows update (if the issue started after a Windows update) or revert to the older version of Windows 10 (if you can). Moreover, check if restoring the system solves the issue for you. If the issue is still there, then either you have to reset your PC to defaults or perform a clean installation of Windows.
