I already posted about this issue on github, and Jon suggested that it might be due to conflicting Python installations. I have now uninstalled everything Python from my system and re-installed Python 3.7 and PsychoPy, but I still get the same error.
I want to create an experiment in which I record participants. I added the ‘Microphone’ response type for this, however, whenever I try to run the experiment I get the following error in the console:
AttributeError: module 'psychopy.sound' has no attribute 'backend_pyo'
I installed the pyo package, and as explained above, tried a lot of fiddling with Python versions, it’s still not working.
OS (e.g. Win10): Windows 10 Pro
PsychoPy version (e.g. 1.84.x): 3.2.4
Standard Standalone? (y/n) yes
