Fix – Update issue 0x803c0109 in Windows 10

Solution 1: Check Speaker Properties

Checking sound equipment and connecting them to an alternate source should be your first step. Additionally, certain upgrades may change your settings, so make sure everything is set correctly by following these steps.

  1. In the Notification box, right-click on the Volume icon.
  2. Make sure the Speakers volume is not muted by opening the Volume Mixer.
  3. Open Playback Devices by right-clicking the Volume icon again.
  4. Set as Default by right-clicking your desired device.
  5. Choose Properties from the bottom of the screen after selecting your preferred device.
  6. Set the Default Format to 16bit 44100hz on the Advanced tab (CD quality).
  7. Check both Exclusive mode boxes on the same tab.
  8. Make a backup of your sound and run it through a sound test.

That should take care of any problems with the Speaker settings. If, however, the issue persists, proceed to the following step.

Solution 2: Manually reinstall the driver

As you may be aware, Windows 10 Update will also install a few drivers on your PC from time to time. That can be beneficial in some cases. On the other hand, generic drivers are not always the best option. As a result, you’ll most likely need to delete Sound drivers and download new ones from the manufacturer’s website. To accomplish this, follow the steps below:

  1. Open Device Manager by right-clicking Start.
  2. Sound, video, and gaming controllers can all be found here.
  3. Right-click on your device and select Properties.
  4. Go to the Details tab.
  5. Select Hardware Ids from the drop-down menu.
  6. Copy and paste the first line into any web search engine (Google, Bing etc.).
  7. You should look up the official manufacturer and support drivers for your sound device.
  8. Install the software after downloading it.

Furthermore, we recommend that you only download drivers from the official site and not from untrustworthy sources. That way, you’ll be safe and get a valid driver’s license.

Drivers are updated automatically

To avoid PC harm caused by incorrect driver versions, we strongly advise utilizing a third-party program to do it automatically.

An automatic program will assist you in safely updating all outdated drivers. Following a series of experiments, our team has determined that the following is the best-automated solution:

A faulty driver might result in a variety of issues.

Solution 3: Restart Update Services

As previously indicated, sound issues are caused by previously installed updates. At least, that’s how it feels most of the time. You may notice performance drops or peripheral device malfunctions due to faulty or incomplete upgrades. This is how you can try to resolve the issue in the first place:

  1. Press Windows key + R and type services.msc
  2. To confirm, press Enter.
  3. Background Information on Intelligent Transfer Service (BITS).
  4. Check to see if the status is set to Running.
  5. If it isn’t already started, right-click and select Start.
  6. Right-click once more and select Properties.
  7. Select the Recovery tab and ensure that Restart service is selected for the First and Second failures.
  8. Save your work and try again.

You’ll be able to verify that the leading update service is operational this way. Next, check to see whether the problem has been resolved by upgrading.

Solution 4: Use SFC to check the system’s integrity

Furthermore, if the updated system files are corrupted or incomplete due to malware or other forms of misuse, a variety of issues can occur. On the other hand, the SFC tool can remedy this in a few simple steps. And here’s how it works:

  1. Run Command Prompt by right-clicking on Start (Admin).
  2. Type sfc/scannow into the command prompt and hit Enter.
  3. Wait for the process to finish before restarting your computer.
  4. Update your software.

Hopefully, you’ll be able to install new updates and potentially fix the sound problem after that.

Solution 5: Remove any last updates

Even if the updates are required, you can still uninstall those that give you trouble. This specific issue affects the sound; however the fundamental cause is a bad update. And if your sound was fine before the update, that’s all the more reason to get rid of them. To do so, follow these instructions:

  1. Type Updates into the Windows Search box.
  2. View the updates that have been installed.
  3. Next, uninstall the most recent update by right-clicking on it.
  4. Finally, save your work and restart your computer.

The majority of the time, Microsoft fixes these issues, so you should expect a remedy in the near future.

Solution 6: Start DISM

If the SFC, as mentioned above scan did not resolve the issue, you could use DISM. In addition, deployment Image Servicing and Management is a command-line program that allows you to re-deploy the system image. Perhaps this procedure will assist with upgrading issues.

The following steps will show you how to start DISM in Windows 10:

  1. As demonstrated above, open the Command Prompt.
  2. Press Enter after entering the following command:
    • DISM.exe /Online /Cleanup-image /Restorehealth
  3. Wait for the procedure to complete.
  4. Your computer should be restarted.
  5. If the DISM cannot acquire files from the internet, try using your installation USB or DVD. Insert the appropriate media and type the following command:
    • DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess
  6. Make sure the path “C:RepairSourceWindows” on your DVD or USB is replaced.
  7. Follow the on-screen directions for the rest of the process.

Solution 7: Run the Update troubleshooter

Almost every article mentions Windows 10’s built-in troubleshooter. And there’s a reason behind that. Microsoft introduced this tool to help end-users with troubleshooting in Windows 10. We can utilize the troubleshooter to resolve update issues because it has remedies for various problems. Hopefully, the system will detect the problem and resolve it for us.

Here’s how to use the built-in troubleshooter in Windows 10:

  1. First, go to the Settings menu.
  2. Next, go to Updates & Security > Troubleshoot to get started.
  3. Next, go to Run the Troubleshooter and select Windows Update.
  4. Continue following the on-screen instructions and wait for the process to complete.
  5. Finally, your computer should be restarted.

Solution 8: Restart Update components

We’ll have to go back to our own troubleshooting if the troubleshooter fails to address the problem. So, the next step will be to reset critical Windows update components in order to restore them to a (hopefully) functional state. This is what you must do:

  1. As an administrator, open Command Prompt.
  2. Run the following commands in Command Prompt once it has started:
    • net stop wuauserv
    • net stop cryptSvc
    • net stop msiserver
    • ren C:WindowsSoftwareDistribution SoftwareDistribution.old
    • ren C:WindowsSystem32catroot2 Catroot2.old
    • net start wuauserv
    • net start cryptSvc
    • net start msiserver

Solution 9: Verify that the BITS service is operational

The Background Intelligent Transfer Service (BITS) is a critical Windows update delivery system component. As a result, the first thing we’ll do is restart it. Any potential interferences should be eliminated as a result of this. Following that, we’ll turn on the service and make sure it stays turned on.

This is what you must do:

  1. Open Services by going to Search and typing services.msc.
  2. Find Intelligent Transfer Service in the Background. For example, restart can be accessed by right-clicking and selecting Restart from the context menu.
  3. Allow for a restart of the process.
  4. Select Automatic from the Startup type drop-down menu on the General tab.
  5. Right-click and select Start if the BITS isn’t running.
  6. Close the window when you’ve confirmed your selection.

Solution 10: Disable antivirus

Antivirus software from third parties and Windows updates are not designed to function together. As a result, it’s possible that your antivirus will prevent the impending update. To be sure, turn off your antivirus for a few minutes and then try installing updates again. The problem will be solved if you succeed.

Solution 11: Manually install the update

Finally, if none of the previous alternatives successfully resolved the issue, we’ll have to give up and manually install the update. Here’s how to do it:

  1. First, make a note of the name of the issued file.
  2. Here is a link to the Microsoft Catalogue.
  3. Copy the name and paste it into the search box.
  4. Save the file to your computer. Keep your system architecture in mind (x86 or x64).
  5. Download and install the update file.
  6. Restart your computer.
  7. Make that the update is up and functioning by checking for additional updates.

That is all there is to it. We hope you can restore your sound and fix any remaining issues.
