How do I set up a microphone for multiplayer steam voice chat?

I have 2 types of voice chat in UE4.

  1. It is done via replicated audio capcure.

  2. It is done all over the map and only triggers when a certain button is held. It’s a walkie talkie.

I need to make the voice chat settings so that the player can choose what microphone the game should capture and also adjust the volume of his microphone.

I don’t know how to do this because I can’t use EOS voice chat since I want to put the game on steam.

It sends screenshots. I don’t send the settings to turn the radio on and off because I don’t think you need it.
