Windows 10 audio stops working after installing Intel Smart Sound Technology driver (version 09.21.00.3755)

Anonymous

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 a compatible audio driver, the new driver overrode it and caused audio to stop working. 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 driver using the following instructions. <ol> <li>From the Start menu, type Device Manager in the search box. Select Device Manager from the search results.</li><li>Find and expand Sound, video, and game controllers.</li><li>Look for a Realtek device, or a device that has a yellow triangle with an exclamation point.</li><li>Click on the device to select it.</li><li>Go to the Device Manager View menu, and then select Devices by connection. <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"> </li><li>Look at the controller device - this should be called Intel Smart Sound Technology driver version 09.21.00.3755.</li><li>Right-click the controller device.</li><li>Choose Properties.</li><li>You should get a dialog like below. Click on the Driver tab as shown:</li></ol>

10. If the driver version is 9.21.0.3755, you have the driver that was sent to you incorrectly. 11. Click Uninstall Device. You will get a popup asking if you want to remove the driver.

13. Check the checkbox as shown, so the driver will be removed. 14. Click Uninstall. 15. When the driver is uninstalled, reboot your system. 16. Your audio (speakers and headphones) should work after the reboot.

I have been unable to resolve my audio problems and there are other problems since this update. I am seriously frustrated and have already been to a technician and paid for this and still have issues. The amount of time I have lost is no joke and I need audio for Skype conference calls with clients. I am disgusted by the lack of action and support from Microsoft on this one. The problems are very widespread and causing significant problems, especially for those of us who work remotely so I think Microsoft needs to step up and acknowledge accountability and provide something tangible to its customers.
