2. Close All Communication Apps Before Running Audacity

Error 9999 can arise because of other messaging and video conference apps, such as Skype, Teams, Google Meet, and Zoom, using the microphone. Such apps can run in the background when you’re utilizing Audacity on the taskbar.

1. To access Task Manager, press that utility’s Ctrl + Shift + Esc keyboard shortcut.
2. Click Processes to switch to that tab if necessary.
3. Select any messaging software listed under Apps and click End task.
4. Then go through the Background processes section to see if there are any messaging apps there. Right-click messaging app processes there and select End task.
5. Also, look in your system tray to see if that includes an icon for a messaging app like Skype or Zoom. Right-click any messaging app icon there and select a context menu option that closes the software.
6. Then open Audacity and try recording something again.

3. Enable Microphone Access for Audacity

Error 9999 often occurs because Audacity is denied microphone access. Enabling microphone access for Windows apps is among the most widely acknowledged error 9999 resolutions to work. This is how you can enable apps to access your microphone in Windows 11/10:

1. Open Settings in Windows 11 or 10 by selecting that app’s Start menu shortcut.
2. Click the Privacy tab or category.
3. Select Microphone to access those app permission settings.
4. Toggle on the Microphone access option if it’s disabled. In Windows 10, turn on the Allow apps to access your microphone setting.
5. Then scroll through the list of apps below that setting and click Audacity’s toggle button to enable microphone access.

4. Reinstall the Microphone Driver

Another possible cause for error 9999 is a faulty microphone driver. Reinstalling your microphone’s driver will address that potential cause. These are the steps for reinstalling a microphone driver in Windows:

1. Bring up Device Manager by right-clicking Start and selecting a shortcut for that utility on the Power User menu.
2. Then double-click the Audio inputs and outputs category to view sound devices.
3. Right-click your microphone and select Uninstall device.

Audacity users have confirmed disabling Host Intrusion Protection in Kaspersky antivirus (security) software fixes error 9999. Host Intrusion Protection is a feature that regulates apps’ activities in Windows 11/10. That component is enabled by default in Kaspersky security software.

Do you have Kaspersky security software installed on your PC? If so, look for and disable a Host Intrusion Protection setting in that software. This Kaspersky online help page tells you how to disable that feature in Endpoint Security for Windows. Or move Audacity to a Trusted app group in that software.

6. Disable Third-Party Antivirus Shields

If you’ve installed a third-party antivirus utility in Windows 11/10, try disabling its shield before running Audacity. You can usually do that by right-clicking an antivirus tool’s icon in the system tray and selecting a context menu option to turn off its shield.

However, some antivirus utilities have special features that monitor microphones, which can block mic access for certain apps. For example, Bitdefender has a Microphone monitor setting.

So, have a look through your security software’s tabs to see if they include any feature setting that could affect microphone access and disable it.
