Audio selection refresh

I’m using audio plugin https://arielfaur.github.io/ionic-audio/2.0/index.html
Similar to the second tab of their demo.

I can play any item using its index, like:

this._audioProvider.play(index);

now I want to stop any item by index. like:

this._audioProvider.stop(index);

but its not working. The slider is not resetting, so, when I play again its continue from the last time.

or
is there a way to reset all audio.
