Windows 10: Microphone not working in Windows RE since 17783

The API winmm waveInOpen return "Undefined external error" in Windows RE since 17783


The error comes from the call to the below API:

[DllImport"winmm.dll"]

public static extern uint waveInOpenref IntPtr hWaveIn, uint deviceId, ref WAVEFORMATEX wfx, IntPtr dwCallBack, uint dwInstance, uint dwFlags;


The test application works fine in Windows RE build 16299.

Performed the test in windows:

when the "Privacy->Microphone->Allow desktop apps to access your microphone" Turned off, the same error return in windows.

when the "Privacy->Microphone->Allow desktop apps to access your microphone" Turned on, the microphone can be open successfully.


Is this problem related to Windows Privacy settings? How can I open these settings in Window RE?

Hi Zarbab,



Thank you for writing to Microsoft Community Forums.



The issue could be because of the microphone being in a disabled state. I suggest you to try the steps listed below and check if it works:

• Open Control Panel and categorize to view by
  Small Icons.
  
• Click on Speech Recognition and navigate to
  Advanced Speech Options > Microphone > Advanced
  
• Check Real Conexant HD Audio, save the changes and exit
  Control Panel.
  
• Restart the machine to see if the microphone works.
