April 21, 2020—KB4550945 (OS Builds 18362.815 and 18363.815): Installed this update and my speakers do not work

Hi. I did the above-mentioned update and my speakers do not work thereafter. Sound is playing but I don't hear anything. When I plug my headset into my laptop, sound can be heard but the usual dialogue box that opens when I plug in, does not appear. How do I rectify this? Please help.

Hi Sree,

This is the reason why a "C" release cumulative update aka optional update should not be installed. Please try uninstalling the same.

Hi Sumit,

Thanks for the help but after I uninstalled the update, the speakers did not work. When I went back to the update history, it is still found there and has not been removed.

It would continue to show as installed. As long as the System information shows 18362.775, you have uninstalled the same.
