Voice chat doesn't work

Hello

I am trying to create online game, but my voice chat does not work.

At first I wrote this in DefaultGame.ini

Then I wrote in DefaultEngine.ini

After that I created MainPlayerController C++ class

On GameMode I set my MainPlayerController to a default class

Voice chat set up on V button

When we are playing on local server it does not work
What am I missing out?

Thank you!

I think you need to use the steam subsystem, are you doing that?

Yes. I turned on steam subsystem plugin and set DefaultPlatformService=steam but that does not help

Can you test it without push to talk first to get that working? Once you got that working, you can integrate push to talk.
Are you running the packaged game over internet with steam? If not, do test that.

You might need the later one here in your .ini file
[Voice]
bEnabled=true

[OnlineSubsystem]
bHasVoiceEnabled=true

Can someone confirm that steam voip works in 4.15? It is already implemented in my project and has worked fine untill the latest release, it no longer functions.
