Sampler sound file variable error
Hi, I am currently working on an experiment in which the different sounds are presented to the participant in each iteration of a loop. For some reason I get a system error when trying to get the name of the file from the loop but it runs fine if I input the file name specifically.
I have tried to run this both from the temp folder the experiment creates and from the hosting folder on two different systems with the same result.
I would appreciate any help you can offer.
Jordan.
Here is the error report:

Hi Jordan,
Could you also provide the code that you use?
Eduard
Sure,
Here is a condensed version ( the original version has a lot more soundfiles attached but the error persists in this version)
Thanks for the help!
Jordan.
Hi,
You can try this suggestion: https://github.com/bastibe/python-soundfile/issues/380
If not, they say that this problem most commonly originates from an incorrect file path. To be honest, I couldn't make it work, during the few attempts that I just gave them.
Alternatively, you can try converting the files to another format. Ogg for example.
Maybe that helps,
Eduard
