Syncing Soundflow in Audacity, Win10/11’s PAudio Challenge

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.
