Animation not playing music or allowing to skip frames

I am relatively new to Animate, starting last month and figured out the basics. I've made animations with a start button and a restart button at the end. No issues.

Now I've tried making an animation without a start button but the audio doesn't play, only upon pressing the restart button. I've read online in other html forums that audio needs to be sort of initialized(?) with a click, which is why it doesn't play without some sort of reader interaction.
A related question is gotoAndPlay(), which upon being used without the context of a reader click stops the animation afterwards (it moves to the frame, plays 1 frame and then stops). Again, with the context of a reader click, this issue doesn't exist.

Is there a way to do both these things without the need for reader involvment?
