Not sure if its useful, but i’ve had a similar issue with sound files on a Dell Latitude E6520 with Windows 7 and PsychoPy 1.85.03b . The following worked fine on 1.83.04 as well.
In a particular builder experiment, I use code to load in some sound files at the very beginning within a code block at the very start in the first routine.
Having this within the “Begin Experiment” area will cause the same segmentation fault error (with no other supporting message to say what caused it).
So sound.Sound(“test.wav”) would give the message every time.
Moving the sound loading code to “Begin Routine” oddly stops the problem from occurring. On more powerful desktop PC’s though, oddly the problem does not occur.
As the laptop is getting on a bit, i’m wondering if there might be a delay fully loading/initializing a particular library in at the stage i’m trying to load the audio now, and hence causing the fault. Moving to “Begin Routine” gives enough time for the library in question to be loaded in, and thus loads the sound files without problem. I’m speculating of course - maybe PYO needs a bit of time to properly initiate on slower machines?
