Does this allow one to e.g. pipe the current audio output on my Mac to my iPhone so I can walk away for a few minutes and keep listening to whatever YT video, Zoom call or Podcast that happens to be playing?

If not, does anyone know of a solution for this? Right now I'm using Jump Desktop which actually does a good job, but consumes lots of extra bandwidth since it also streams the Mac's screen (at near 30fps).
