Problem "Bug" with loading picture with audio

[Akbar]

Hi Jeremy,

My participants reported about an issue they encounter when doing the task in PC. Ibex. This issue did not occur at every attempt though. Some participants successfully completed the tasks. But, unfortunately, some have this issue. I wonder if you can give me the solution. The participant tried halfway until the picture stucked and after waiting several minutes, no sound has been played nor is the page responsive.
He managed to look at the browser console and saw that a resource failed to load.
for your info, CheckPreload applied.
Here the demonstration link: https://farm.pcibex.net/r/lNxusI/

I am looking forward to your suggestion.
Many thanks,

Hi,

I was able to reproduce the problem, and it doesn’t look like it’s coming from a filename mismatch: in my case, the file A10-3.mp3 failed to play, and it looks like my browser never even sent a request to fetch it. PennController keeps only up to 4 pending requests in parallel, to prevent flooding distant servers with requests. It could be that sometimes, 4 audio files fail to fully preload, so PennController never gets to the remaining resources. In my experience, this is more likely to happen with Firefox (and when requests lots of resources) because of the way it loads media streams. I have updated the way that preloading is detected in PennController 2.1beta, so you could try overwriting the copy of PennController.js from your project’s Modules folder with it, and hopefully that should address the issue
