PsychoPy version (e.g. 1.84.x): 1.90.1
Hello,
I am new to psychopy and have followed some tutorials to include .wav files in a spreadsheet, and after a few errors like needing to convert sample rates I received no errors and my script ran as planned with the text stimuli. However, I could not hear my sounds! Below are the messages I got after pressing escape and the script. Thank you very much!
When I pressed “escape” after not hearing anything, I received this if that is useful:
27.8915 WARNING Couldn’t measure a consistent frame rate.
