Enable the Windows Audio and Endpoint Builder Services

Many Audacity users have reported that the Internal PortAudio error can be fixed by turning on and running the Windows Audio and Endpoint Builder services that were turned off. So, if one of these services is turned off on your PC, this fixing method is likely to work. Here’s how to check if these services are running and turn them on in Windows 11/10:

4. Then select the properties window’s Start option to run the service.
5. Click Apply and OK to save the options and exit the Audio Properties window.
6. Repeat steps four to eight for the Windows Audio Endpoint Builder service.

1. Open the Audacity window.
2. Click Transport on Audacity’s menu bar.
3. Select the Rescan Audio Devices option.

Manually Enable all Playback and Recording Devices

It’s possible that the PortAudio error is caused by an audio gadget that can’t play or record sound. Because of this, you should turn on all playback and recording devices that are turned off in the Sound box. You can do that by doing these things:

1. To access the Run dialog, press Win + R.
2. Type mmsys.cpl in Run’s command box.

8. Select the Sound window’s Apply option to save settings.
9. Click OK on the Sound window to exit, and then restart your Windows 11/10 desktop or laptop.

Reinstall Audio Device Drivers

The Internal PortAudio can also be caused by a problem with the driver for a sound device. Some people can fix this problem by reinstalling the drivers for all audio devices. Try the following to update your PC’s audio device drivers:
