3] Enable All the Necessary Windows Audio Services

Many users have reported fixing the issue by enabling certain Windows audio services. These services are Windows Audio and Windows Audio Endpoint Builder.

However, you can easily enable these services by following the below steps:

  • Press Windows Key + R to launch Run.
  • Type services.msc and press Enter.
  • Now look for Window Audio service and right-click on it and select Properties.
  • Over here, make sure the Startup type is set to Automatic. Also, if the service is not running, click the Start button.

  • Finally, click on Apply > Ok.
  • Repeat the same steps for the Windows Audio Endpoint Builder service.

Once both services are enabled, reboot your PC, and it should work for you.

4] Reinstall All the Audio Device Drivers on Your PC

It is possible that the issue could be because of a corrupt audio drive, and hence we recommend you reinstall the driver.

When uninstalling, ensure not only to remove the audio driver but also any related software. Follow our detailed guide on installing the audio driver on Windows PC. 

Windows no more installs drivers automatically, and even if an update is available via Windows update, we recommend downloading from the OEM.


So those were some of the quickest steps that you can take to fix the Audacity Internal PortAudio error on a Windows PC. You can also try other recording apps to see if you can record your voice. If not, you should check your microphone and other settings on your PC.
