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

OS (e.g. Win10): Win10
PsychoPy version (e.g. 1.84.x): 2023.1.2
Standard Standalone? (y/n) If not then what?: yes
What are you trying to achieve?: I want to play audio in my experiment : one first long stream (exposition phase), then shorter streams (trials, they change in a loop).

What did you try to make it work?: I have one routine with the long stream, and another one in a loop with a file owning all the short streams.

**What specifically went wrong when you tried that?:**Traceback (most recent call last):
the long stream works, but the short stream happen juste one time, then every thing stops and this message appear :
File “C:\Users\ACER EXTENSA\Documents\neurosciences\stage\S_peperkamp\adultes\library\essai_lastrun.py”, line 337, in
elif sound_1.isFinished:
AttributeError: ‘SoundPTB’ object has no attribute ‘isFinished’
################ Experiment ended with exit code 1 [pid:14700] #################

I have read this was a bug in the 2023.1.2 version, so i have tried to update the version, and this message appeared :

File “C:\Program Files\PsychoPy\lib\site-packages\psychopy\app\connections\updates.py”, line 406, in onInstall
info = self.doAutoInstall()
File “C:\Program Files\PsychoPy\lib\site-packages\psychopy\app\connections\updates.py”, line 554, in doAutoInstall
v = self.latest[‘version’]
TypeError: ‘int’ object is not subscriptable

I have tried as well to download the 2023.1.3 version, but there is no .exe file in the zip, I don’t know how to use this

can someone give me some advise?

Thanks!!!

Hello,
Instead of using version 2023.x.x, use the previous stable version, 2022.2.5:

Release PsychoPy 2022.2.5 · psychopy/psychopy

Because of this exact bug, I have 2 versions of PsychoPy on my computer.

Let me know if it works for you,
Chen

Thank you !

• first, thanks to you, I have realized I didn’t use the right link to install 2023.1.3, I achieved installing this version. Anyway, this version didn’t work either, although I have read it should work.
• I have thus tried your version, it works! thank you very much!

Perfect, no problem!

Hi, forgive my ignorance! I think this might be a solution to my similar issue here:

Audio problem: selecting PTB as preferred audio engine in v2023 1.2

Ok so I’ve found where I select the PTB library under settings - audio. However, when I run the experiment now, it gets through one presentation in the first loop, and then crashes when it comes to the next presentation within that first loop, with this error: 70.2505 INFO Loaded monitor calibration from ['2022_09_22 09:31'] 70.4948 INFO Investigating repo at C:\Users\___________\Research\Online Stroop\verbal_load_no_async 96.0607 INFO Loaded monitor calibration from ['2…

However, I can’t seem to find the folder location C:\Program Files\PsychoPy\Lib\site-packages\psychopy\sound.

Psychopy seems to be installed to this folder, but there is no Lib folder in that location (or any other folder)

C:\Users____\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\PsychoPy-2023.1.2

any idea how can we fix it for mac installation. Where can I find this path in mac and replace the file with the one available here?

I have the same problem with the audio failure and have been confused for several days. I just tried your version and it did work! Thank you sooooo much!!

Another solution is to set the Use PsychoPy version to 2022.2.5 in the settings:
