Multimedia icons and arrow icons can be found on sections "Media" and "Navigation" of the new Icon Library.

(Link to Figma file on the comments)

Figma note: The Layer 02 of each arrow icon contain the filled form of the arrows. These Layers are hidden to keep the arrow icons without filling by default. For this example is recommended to unhide the Layer 02 of the arrows "up" and "down" to be used on the example. The same applies to the "play" and "stop" buttons on the Media section.
