Hi, and thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.
I understand the issue you have, there is nothing to worry I am here to help, the .Net framework can affect the functionality of the audio, however, this might be an incompatibility issue with the audio driver, moreover, kindly follow the steps below for us to sort out the issue:
-Press the Windows key + X
-Go to Device Manager
-Expand the Sound, video and game controller
-Look for Realtek (R) Audio or High Definition audio
-Right-click and click "Update Driver"
-Look for "Browse my computer for driver"
-Click "Let me pick drivers available drivers on my computer"
-Choose an old driver or other names of the driver then select it and hit next until it installs.
