Some sound files don’t play

This experiment uses auditory stimuli, and most of them play fine, but two particular sound files don’t — when thsoe should be presented the experiment gets gets stuck on that “Please wait while resources are loading, this may take 1 minute screen”, then eventually it goes past them without playing the sound (it still presents the text that goes with them and waits for me to press a button, it just doesn’t anything) and the rest of the experiment works fine, it just refuses to play these two sounds any time they come up.

I’m pretty sure the issue is the file itself, not a problem in the .csv Template or whatnot. (This happens even when I present them outside the template – e.g. I tried creating a separate newTrial hardcoded to present just that particular sound and that sound still fails to play, even when it’s not coming from a .csv list. I had thought maybe the sound filename was messed up – like maybe there was a hidden character somewhere, or the .csv versus the actual sound file had some letter that looks the same to me but was actually a different Unicode or something, like g vs. ɡ – but the problem still happens even when I rename the file.) These also rule out the other possible issues from the FAQ, I think (e.g., the problem isn’t explained by the filename being misspelled somewhere or by a blank line at the end of the .csv, as far as I can tell).

Weirdly, the file still plays from preview (if I just click on it in the Resources list and then click the “play” button on the little in-browser player), and I can’t see anything wrong with it in Praat, so it doesn’t seem like the file itself is corrupt or anything. It just refuses to play in the experiment itself.

For reference, one of the sounds that doesn’t work is “pja20.wav”, which occurs within the first four trials of the experiment (these first four trials are four practice trials played in a random order, so you may experience this error anywhere between trial 1 and trial 4). The other sound that doesn’t work is “pei20.wav”, which occurs randomly somewhere else in the experiment.

Thank you!

(Quick update on this: after further testing we found that this issue seems to be happening in Firefox but not other browsers [at least not Chrome or Safari], and it also doesn’t happen if the soundfiles in question are converted from .wav to .mp3. So, I still don’t know what the cause of the problem is, but at least there is a workaround.)
