[nabs-l] Playing audio on the slides

[Elif Emir Öksüz]

Hi all,
I am taking an online course. The professor adds audio to each slide,
but in order to play the audio, students need to click speaker button
appears on the right corner. Some people make them automatic so, when
I activated slide show mode,  audio plays with the each new slide.
This one need individual activation on each slide, and I am not able
to do that.
Does anyone know how to listen the audio on the slide?
