Hello PsychoPY community,

I am weirdly having some issues regarding a sound component in my experiment. I am saying “weirdly” because everything works fine on the computer in my office, also on the computer at another lab but for some reason I get errors and experiment crashes when I try to run it on the computer at the lab I will be working on.

The first error can be seen below (I am accessing a sound stimuli in a folder and I get this error. If I produce a sound within PsychoPY though, it works. But it is not what I want to do) :

Another issue is that I have an excel coloumn where I define the duration of the sound component. And I index to these durations by, e.g. writing $duration\_sound in the properties of my sound component (I put the $duration\_sound in the duration field). Some duration values however are 0 because in some trials, I do not want the sound to be played. This works well in ohter computers as I said but in this computer, I get this error:

Any ideas would be appreciated!
