REAPER: Troubleshooting

  • I get “Error opening devices” when swapping to WASAPI!
    REAPER showing an error that says 'There was an error opening the audio hardware. WASAPI Error: could not find input device'.
    • Could not find input device: You either don’t have a microphone connected or your formats are (i.e. speakers at 48,000 Hz and microphone at 44,100 Hz).
      If it’s the former, change the “Input channels” to “0” in the Device section of Preferences.
      If it’s the latter, make sure your microphone matches the format of your output device.
  • RBN Preview doesn’t load!

    • You really shouldn’t be using this anymore but if you insist, download the appropriate Microsoft Visual C++ Redistributable Runtimes.
