All of a sudden my microphone stopped working on all Desktop Software in Windows 10. I have reinstalled all related drivers and updated anything that was needed. When I am in the driver software (Realtek HD Audio Manager) I can hear the microphone input when I set the output volume to high so I know it is not a hardware issue. But when I try to access it in any other software it just stays quiet and no input is recorded even though the correct microphone shows up in the settings. Has anyone got an idea what could be the problem
I encountered this problem, too. Wasted an hour until I found this post. For future reference, the errors reported are dependant on the selected audio subsystem the Windows Audio Session reports
DEVICE_INITIALIZE: Access Denied
, but DirectShow saysCREATECAPTUREBUFFER Error {0E7D21D9-C040-4F36-AEEF-CAC3C3CE6C10}
, which is the most non-informative error description I have ever seen. Most applications (Skype, Windows Audio Settings) will silently ignore these errors anyway, so you are simply stuck with a non-initialized input. – Hermann – 2019-01-01T17:14:10.947
