How to make Audio Broadcast System with Unreal Engine

It is a simple setup that includes writing small blueprints code in a project.

Enable Pixel Streaming Plugin in the plugin.
Go to player controller or character blueprint.
On Begin Play node, add ‘get pixel streaming delegates’ node.
From its return value, get the “bind event on new connection” node.

Now make a new Blueprint actor and add a Pixel Streaming Audio Component to it.
Grab that Audio Component and create a new “Listen To” node.
Make a custom event and make the “Player to Listen to” an Input of that custom event.
Now go back to the main player controller blueprint or character blueprint where you bind an event on new connection in Step 4.
On New Connection, Spawn actor from class and choose new actor that you created.
When spawned, call the custom event that was created.

Now package your application and upload to Eagle 3D Streaming Control Panel and test your application. On application start, the Audio Broadcasting will work.
