Microphone component issues

OS (e.g. Win10): Win10 64bit
PsychoPy version (e.g. 1.84.x): 2021.2.2
Standard Standalone? (y/n) If not then what?: yes

Hi everyone,

I’ve been using PsychoPy for a couple of days only (+ a total beginner with Python) and I’m facing an issue that I can’t seem to be able to resolve despite having spent quite a lot of time on forums. I’m trying to build a fairly simple reading task in which a few sentences are randomly presented to subjects. Subjects are asked to read the sentences once they are presented to them. Everything seems to be working fine until I add the microphone component. I’ve tried to play with a bunch of different hardware and audio preferences*, based on what I could read on forums and warning messages, but no success until now. I would really appreciate if anyone could give me some insights as to what the problem is and/or what I could do to fix it. Here’s the error I get :

Traceback (most recent call last):
File “C:\Users\lburin\Desktop\TEST\”, line 457, in
File “C:\Users\lburin\AppData\Local\PsychoPy\lib\site-packages\psychopy\sound\”, line 803, in stop
“Cannot stop a stream that has not been started.”)
psychopy.sound.exceptions.AudioStreamError: Cannot stop a stream that has not been started.

Experiment ended. #####

*I’ve moved PTB first in the Audiolib after I got some warning message, but also because if I get rid of it I can’t seem to be playing any soundfile (I need that for an another task, a repetition one, and for which I seem to have the same problem with the microphone component).



Thank you for reporting this issue. We currently investigating the cause of the error.

We’ve managed to fix the issue. The problem came from the fact that the stop duration for the microphone component shouldn’t be left blank!
