Microphone input not working in Windows on simple naming experiment

Dear all,

I cannot record audio from the microphone using the builder. It just crashes when it runs to the Microphone Component. I am not sure if it is a problem with my computer or the programming language. The error message is as below:

6.7153 WARNING User requested fullscreen with size [1366 768], but screen is actually [1920, 1080]. Using actual size
8.0611 WARNING Starting Microphone but sound lib preference is set to be [‘sounddevice’, ‘pyo’, ‘pygame’]. Clashes might occur since ‘pyo’ is not preferred lib but is needed for Microphone

Tested with Psychopy 3.1.2. Thanks a bunch!


What are the settings in your PsychoPy preferences for the sound driver? Make sure that the directsound is listed (on Windows systems) as below

Thanks a lot, Jon. I tried using all the specification as shown on your screenshot (apart from the last item on ‘parallel ports’ since I can’t see this, although I am not sure it is critical), the same problem still remains:
