Hi Mohsin,

• Are you referring the missing driver as the High Definition Audio device
  with a yellow mark in the screenshot?

This issue could have happened due to corrupted driver files. Let's try reinstalling the driver and check if the driver can be recovered. Follow the below steps to re-install the driver.

• As you are already on the device manager, right-click on High Definition Audio device, and select
  Uninstall.
• Restart your PC and Windows will attempt to reinstall the driver.

If the issue still persist, I suggest you to run the hardware troubleshooter and check if the issue is resolved. Follow the below steps to run the Hardware troubleshooter;

• Type troubleshooting in the search tool.
• Click on Troubleshooting tab.
  
• Click on view all option on the upper left corner.
  
• Select the Hardware and
  Device options from the list.
• Click Next to run the Hardware
  and Device Troubleshooter.

Intel High Definition Audio Driver

I had this exact same problem after downloading the first cumulative update and some drivers a few days after installing version 1809. The old driver should still be kept on your system; you shouldn't need to download anything. What makes this problem especially
confusing is that, (at least in my case) it needs a "Realtek High-Definition Audio" driver, because the actual hardware was made by Realtek Semiconductors, and is merely based on an Intel standard. The procedures I used are:

1. Go to Devices and Printers in the Control Panel
2. right click on your computer's name and click properties
3. click the hardware tab, the malfunctioning device should be at the top of the list (indicated by something like a yellow triangle in the bottom right corner of its icon)
4. click properties for the malfunctioning device
5. in the individual device property window click change settings
6. go to the driver tab and click update driver
7. Click the second option browse my computer, then click let me pick
8. under manufacturer select Realtek, then select Realtek High-Definition Audio and continue with driver installation

This should reinstall the original Realtek High-Definition Audio
driver.
