Audio cannot be played

hi, so I inputted 4 audio stimuli, but when I run it, only one audio plays. How can I fix this?
(I’ve made sure the Excel file names are the same.)

Try setting the start time to .2 seconds

thank you so much! but i think my problem is not because the time start, it because i haven’t change the audio library to ptb (i don’t know if this is the problem)

once again thank you for your help!
