Hi,

I have a script that displays a sound half way through, this works on one laptop, however, when I change it to another laptop the script immediately breaks with the following errors;

File “C:\Users\maitland-local\Desktop\DASH\DASH Task\_lastrun.py”, line 1315, in   
run(

soundfile.LibsndfileError: Error opening ‘bleep-41488.mp3’: Error : bad data offset.

I have tried changing the audio library but not no effect.

Thank you for any help.

What did you try to make it work?: I have tried change the file name to .aiff and I am sure the path should have no errors. I also installed FFmpeg…
