I have create a course in Courselab. I am facing problem with the audio button. I have text boxes on the screen which appear as audio plays. While audio is playing if I click the sound off button, the audio stops. But if click the audio button again to make the audion on, the audio doesn't start. Can anybody tell me the solution for this problem?

Hi, SR,

Not sure, but maybe using the Video object in hidden mode (it can play audio too) could be the solution. Video object has explicit PLAY/PAUSE/STOP methods, that you can call on the same button click.

so does that mean that the SOUND ON/OFF button doesn't work? I've encountered the same problem too!
