How can I stop audio playing in Rise when a Storyline block is clicked?

Hello Victoria,

One way to prevent your learners from playing a multimedia block and an embedded Storyline 360 block simultaneously is to add a 'Continue' block between the two, and then use the 'Complete Block Directly Above' setting so that your learners will first have to complete one block before going to the other. 

Here's a sample course which demonstrates how the 'Continue' block can be used to make sure that one block is listened to completely before the other one can be accessed:

Hope this helps!
