Cannot grant access to microphone

ActivePresenter Support Questions
1

Problem:
This is the error I keep getting on two different devises:

ActivePresenter
There is something wrong with the audio device and most often due to:

  1. ActivePresenter doesn’t have permission to access the microphone. You must go to
    Windows Settings > Privacy> Microphone to grant access.
  2. A lost connection to the audio device.
  3. The device itself may be faulty.

ActivePresenter version: 8

OS: Win 10

Notes:

I have tried everything. No webcam or audio feed. There is nothing in the privacy settings stopping this. This a bot of the log:

Hi Fred,

Do you use any virtual audio device? If yes, please try disabling it then restart the program to see if it helps. Or, you can try the following steps:

  • Uninstall the audio driver.
  • Restart your computer.
  • Install the latest driver from the hardware manufacturer.

Regards,

Hi there,

Thank you very much for the response. I do not use any virtual audio devices.

I checked the driver and it seem to be up to date. How do you uninstall them? In Device Manager I see that I can uninstall the driver under sound. I guess I can do that. But how do you install it back after that step?

Regards,
Farhoud

Hi Fed,

If you don’t know where to download the driver, in the Device Manager window, you can choose one of the following:

  • Right-click the device and select Update Driver.
  • Select Action > Scan for hardware changes.

Hi there,

I just did and restarted the computer. No change unfortunately.
