Advanced Action - Toggle on and off Audio

Hello,

I have added smart shapes into my project on each slide with an advanced action that when clicked plays audio and when clicked again stops the audio.  If the learner clicks to listen to the audio but does not click to turn the audio OFF and progresses to the next slide they have to click the audio button twice on the next slide to start the audio.  I understand why this happens –this button uses a user variable, if you click on the audio button to listen and then click to the next slide without turning the audio off the variable essentially keeps the value of ‘1’ (thus meaning captivate still thinks the audio is playing).  So when you click on the audio button on the next slide it essentially turns off the audio (value of ‘0’)  and then you have to click to start the audio (back to a value of 1). 

Does anybody know if there is a way around this?  I have attached some images:

Any help with this would greatly be appreciated
