Allow seeking set to NO on slide layer not working

I found a thread with javascrip to hide it

I want to freeze it as well. The user experience is bad by design when the layer has animations covering the base layer and there is no audio on the layer, but dragging the seekbar allows a learner to hear the base layer audio.   

I'm wondering if there is a way to stop the audio from playing on the base layer when seeking on the layer is set to no with a trigger.

It's only 2 of 30 slides, so I can't use the player to globally effect this.

I'm wondering why there are not more people posting about this, unless they found a solution.

The javascript I found to hide the seekbar is $('div.controls-group.control-bar.cs-seekcontrol.progress-control').hide();

My other solution is making the layer a dialogue layer, but it's blocking the entire player - how nice would this dialogue layer be if there was no dimming of the player, but just like the next button, we can disable it - see it, but not interact with it.
