I forgot to mention that there have been problems with the Realtek drivers and devices and Windows 11. I have the Realtek sound hardware and cannot record anything using any number of various drivers and settings yet it works fine in Windows 10.
I am using dell Inspirion 3511 (Windows 11) from past few days, I am using Realtek audio driver. But the microphone is not working at all, Even when I connect my earphones then also the microphone isn't working.  I am sure that I have checked all my sound settings, troubleshooted a couple of times, everything is enabled, when I run the tests it is showing 100% output, but the microphone is NOT working on all of my apps (like WhatsApp, teams, zoom, etc.) .  Should I try uninstalling current driver and re installing it? If yes how to reinstall the same driver?? Please fix this issue.
