Using microphone as a response option

If this template helps then use it. If not then just delete and start from scratch.

OS (e.g. Win10): Mac OS 10.14.6
PsychoPy version (e.g. 1.84.x): 3.2.4
Standard Standalone? (y/n) If not then what?: Standard Standalone
What are you trying to achieve?: I’m building a study with a visual stimulus, and I’d like to record RT of the verbal responses.

What did you try to make it work?: I selected the microphone under the “Response” category.

What specifically went wrong when you tried that?: When I tried to run the script, I received the following error message. It’s my first time using this feature. Any help will be much appreciated. (As an aside, the script runs fine if I delete the microphone component as a response option.)
