OS (e.g. Win10): Win10
PsychoPy version (e.g. 1.84.x): 2020.2.10
Standard Standalone? (y/n) If not then what?: y
What are you trying to achieve?: I’m trying to set any sound file dynamically in a loop with the PTB sound library.
What did you try to make it work?: I have an experiment I haven’t worked on in many years that I’m trying to tweak for a new context. In the experiment, the path for a sound component is set dynamically as a part of a loop (using “set every repeat”). When I try to run an experiment using this format and the new PTB library, the experiment doesn’t run, giving me the error above. I created a toy version with just the loop that’s causing me problems, and it still breaks; I also created a toy version with a completely different set of stimuli, and it still breaks. It works fine with the pyo, pygame, and sounddevice libraries. None of my sound files I’m using are 48000 Hz; they’re all 44100 Hz. The files work fine when the filenames are not updated dynamically (when they’re “constant”), and, oddly, they work fine when they’re set dynamically by a Code component in a different Routine (which is a setup I have in a slightly different study using identical stimuli).
I was hoping to switch to using the PTB library, because I’m getting some odd other errors when I use the other libraries (I’m trying to provide audio feedback that updates as a result of button presses and it’s throwing a different error for only certain sound files, unrelated to the ones triggering the error here), but this experiment mostly seems haunted.
I’ve put in a request to update PsychoPy on my system to the latest version, but my university requires tech support to update any software, so it might take some time.
What specifically went wrong when you tried that?:
pygame 1.9.6
