I don’t hear my voice playback – is this normal? I have tried inside the editor and also as right-click launching the project. I’m in version 4.26.

Do the voice comms only work in a packaged/launched game?
Do only other players hear my voice?
Am I meant to hear playback?
Are there other steps if I want to connect with other players over steam?

Here is my DefaultEngine.ini

[OnlineSubsystem]
DefaultPlatformService=Steam
bHasVoiceEnabled=True

[Voice]
bEnabled=True

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480

[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName=”OnlineSubsystemSteam.SteamNetConnection”

And my DefaultGame.ini
[/Script/Engine.GameSession]
bRequiresPushToTalk=true

It works perfectly on Windows and should work on iOS and Android as the engine functionality does exist but I haven’t verified it.

I always just use an Execute Console Command node and type servertravel yourmapname. This will automatically transfer all clients to a different map without a multicast event. Servertravel is only ran on the server so the multicast event isn’t required.

I don’t have an exact solution for your second issue as UE 4.25 has some issues with registering talkers. A solution could be to add a delay node on your begin play event (~1 second) then register the talker. After this run the normal voiptalker code.

also I am using steam sockets with seamless travel. You have to package the game to test a game with steam sockets sadly.

Actually I think it’s a problem with registering the talker after a transition… Not sure how to solve that. I’m trying to register talker when the map loads but it’s only half-working. Any idea how to register a talker on map load?

4.25. I’m just making the server call a multicast that calls a replicated servertravel to a new map. I’m using a tranisition level, and both maps are seamless enabled. My VOIP push to talk button is on my Character, should it be on my PlayerController instead?

I have many projects that use Seamless server travel and the voice functionality works correctly on Unreal Engine 4.23. How are you travelling between maps and which engine version are you using?
