Ok, so I solved the problem of the triggers adding the I/O component at the very top of each sound trial, so that the trigger was the first to be read in the loop. But the problem with the audio files persist and some sentences, mainly the longer ones, are cut. Audio lengths vary from around 3.6s up to around 6.6s. I have been trying to implement the tricks suggested in another discussion entitled: Some WAV files don’t play in full, but they do not work for me either. The ISI static component is added but I am not able to change libraries to ‘pygame’ or ‘pyo’ because the experiment is not able to run. With the ‘pyo’ lib I was reported some errors in the boot that I do not know how to check and with the ‘pygame’ library does not report any error at all. Do you know what can be causing this problem and what should I do to play the full audio files? Thank you!
