Audio capture crash

OS (e.g. Win10): macOS 10.12.5
PsychoPy version (e.g. 1.84.x): 1.85.2
Standard Standalone? (y/n) If not then what?: Yes
What are you trying to achieve?: Audio capture with microphone to record subject’s voice response

What did you try to make it work?:

Adding a Mic device resulted in a crash (see error log below). I then added ‘sounddevice’ to the audio library (PsychoPy Preferences) and removed ‘pyo’. This resulted in the same error. Thus, PsychoPy still seems to use the ‘pyo’ library for audio capture? I also removed ‘pygame’ from the audio library, leaving only ‘sounddevice’ but that also resulted in a pyo server error.

What specifically went wrong when you tried that?:

pyo version 0.8.6 (uses single precision)

Does anyone have an idea how to get the audio capture to work?

I am having the same problem. Has anyone found a solution to this?
