How to Fix Audacity’s Internal PortAudio Error in Windows 10 & 11
Audacity’s Internal PortAudio error can be tricky to fix. Check out this guide on how to get it repaired on Windows 10 and 11.
Audacity is great music editing and recording software when it works. However, some users can’t utilize Audacity because of an Internal PortAudio error that occurs when they launch the software. Instead of launching, Audacity throws up this message: “Could not find any audio devices… Internal PortAudio error.”
Although the Audacity window opens, users can’t play or record anything with that software when the Internal PortAudio error occurs. Does the same thing happen when you run Audacity? If it does, this is how you can fix the Internal PortAudio error in Windows 11 and 10.
1. Run the Playing Audio Troubleshooter
Windows has a “Playing Audio” troubleshooter to help users resolve audio playback issues. As the Internal PortAudio error breaks sound playback in Audacity, that troubleshooter could be useful for fixing this issue. You can access the Playing Audio troubleshooter in Windows 10 and 11 via the Control Panel like this:
- Click a search box or magnifying glass icon on the Windows 11/10 taskbar.
- Then type in Control Panel within the search utility.
- Select Control Panel to open that app’s window.
- If Control Panel opens in its category view, click Large icons on the View by menu.
- Select Troubleshooting to access that applet.
- Next, select the View all navigation link on the left of the Control Panel window.
- Click Playing Audio to launch that troubleshooter.
- Select the troubleshooter’s Next option to continue.
- Then select one of the sound output device options to troubleshoot and click Next.
- Apply the resolutions suggested within the Playing Audio troubleshooter.
2. Enable the Windows Audio and Endpoint Builder Services
Many Audacity users have confirmed enabling and running disabled Windows Audio and Endpoint Builder services can fix the Internal PortAudio error. So, this troubleshooting method will likely work if one of those services is disabled on your PC. This is how you can check and enable those services in Windows 11/10:
- First, bring up the Windows search box and search for Services. You can also use one of the other ways to open Services on Windows.
- Next, double-click Windows Audio to bring up further options for that service.
- If the service is disabled, select an Automatic startup option on the drop-down menu.
- Then select the properties window’s Start option to run the service.
- Click Apply and OK to save the options and exit the Audio Properties window.
- Repeat steps four to eight for the Windows Audio Endpoint Builder service.

- Click Transport on Audacity’s menu bar.
- Select the Rescan Audio Devices option.
- Wait for the rescan to finish, and then restart Audacity.
