Hi everyone !
I am desperate. I have an experiment that works perfectly fine on my own MacOS computer, and on the MacOS laptop of my supervisor. But after sending it to my second supervisor, on Windows, the experiment does not handle the sound feedback anymore.
The sounds are two .mp3 files. They can be opened and played independently on the Windows computer, outside of psychopy. But whenever we try to run the script, it ends with this error :

We also tried to convert the files to .wav, but same issue. Then we tried with other .wav files, used successfully in other experiments previously, but we got another error “malformed ‘fmt’ chunk”…
When we remove the sound feedback, the experiment runs perfectly on Windows. What could be the problem and what can I do to fix it ?
Thank you so much for your help !
