Superlab 6 - pairing two lists (pictures) and (audio) in order to present them simultaneously

Hi everyone. I am trying to pair two lists (pictures) and (audio) in order to present them simultaneously.

I have read several documentation, but it’s not clear what to do.

Depending on stimulus definitions, sometimes I get only sound or pictures, but never both at same time.
Can anyone help, please? To date I got no solution.

Many thanks in advance

Can you post your experiment?
