I'm a local IT Consultant. Yesterday I had a client with an HP All in One Windows 10 desktop with this exact problem. Reinstalling the Realtek driver from the HP support web site fixed the problem for me... ut for how long.. who knows?

| Earlier this week, Intel unintentionally released version 9.21.00.3755 of the Intel Smart Sound Technology (ISST) Driver through Windows Update, and inadvertently offered it to a range of devices running Window 10 version 1803 or 1809. If your device contained<br> a compatible audio driver, the new driver overrode it and caused audio to stop working.<br><br><br><br><br><br>We are working with Intel to resolve this issue, and as soon as we learned of the issue on October 11, we made sure the driver was no longer being offered through Windows Update. If it was already installed on your device, you will need to uninstall the<br> driver using the following instructions.<br><br> <br><br> <br><br><ol><br><li><span style="color:#333333">From the Start menu, type <strong>Device Manager </strong><br>in the search box. Select <strong>Device Manager</strong> from the search results.</span></li><li><span style="color:#333333">Find and expand <strong>Sound, video, and game controllers.</strong></span></li><li><span style="color:#333333">Look for a Realtek device, or a device that has a yellow triangle with an exclamation point.</span></li><li><span style="color:#333333">Click on the device to select it.</span></li><li><span style="color:#333333">Go to the Device Manager <strong>View</strong> menu, and then select<br><strong>Devices by connection</strong>.<br><br><br><br></span><a href="https://learn-attachment.microsoft.com/api/attachments/048ccab5-e448-412c-b600-b4b3aea9fe18?platform=QnA target="_blank" rel="noreferrer"><img src="https://learn-attachment.microsoft.com/api/attachments/048ccab5-e448-412c-b600-b4b3aea9fe18?platform=QnA style="color:#333333"><br><br></span></li><li><span style="color:#333333">Look at the controller device - this should be called<br><strong>Intel Smart Sound Technology driver version 09.21.00.3755.</strong></span></li><li><span style="color:#333333">Right-click the controller device.</span></li><li><span style="color:#333333">Choose <strong>Properties.</strong></span></li><li><span style="color:#333333">You should get a dialog like below.

2018-10-15T14:14:31+00:00 Aside from uninstalling the said driver. You can manually update it.
Right click Intel Smart Sound Technology driver> Choose update driver > Click "Browse..." > Let me pick from a list of drivers > Uncheck "Show compatible hardware" box > Click/Choose "Microsoft "as the Manufacturer > Choose/Select "High Definition Audio Controller" > Click Next > Follow the prompt.
After this, try playing a sound on your PC.

"PattyPorenta Hansen" uninstall your audio driver completely from 'Device Manager' (as described above) e.g. Realtek HD Audio or whatever your audio driver is, then reboot your computer, this should roll the driver back to a generic driver that works, test your audio, if it does not work, go to 'your comp manufacturers' support and select drivers, download the last audio driver that they have for your comp.
