Photon Voice - UserId is empty, connects but can't bind players

Suspensorio · November 2018

I have this project to deliver, it's a simple one: one player creates a room, then other players enter this room. The room creator can manipulate one object, the other players, only see the manipulation result (simple transformations). Also, the room creator can transmit voice to the other players.

I followed the tutorial for Photon PUN 2, and set up the game as instructed. The networking part is working fine, the room is created, players connect, and the object is synchronized with everyone.

The problem is with Photon voice. I also followed the instructions, and set it all up. Apparently, it connects, but the UserId is sent empty to the connecting player, which doesn't let voice to be sent.

Could you help me in figuring out what part of the setup and/or initialization process I'm missing? Tried searching the forums already, looked into source code, but I'm out of clues.

Here is my configuration:

Photon Server Settings:

Photon Voice Network and Recorder:

A Photon View (don't know how necessary it is):

And this is the basic initialization code:

public class PhotonController : MonoBehaviourPunCallbacks
{
....string gameVersion = "1";
....string roomName = "baseRoom";
....public byte maxPlayersPerRoom = 4;

....private void Awake()
....{
........PhotonNetwork.AutomaticallySyncScene = true;
........DontDestroyOnLoad(gameObject);
....}

....void Start()
....{
........PhotonNetwork.GameVersion = gameVersion;
........PhotonNetwork.ConnectUsingSettings();
....}

....public override void OnConnectedToMaster()
....{
........base.OnConnectedToMaster();
........// opens UI, waiting for user to create or join room
....}

....// Button to create room
....public void _StartServer()
....{
........if (PhotonNetwork.IsConnected)
........{
............GlobalSettings.iAmServer = true;
............PhotonNetwork.CreateRoom(roomName, new RoomOptions { MaxPlayers = maxPlayersPerRoom });
........}
....}

....// Button to join room
....public void _StartClient()
....{
........GlobalSettings.iAmServer = false;
........PhotonNetwork.JoinRoom(roomName);
....}

....public override void OnJoinedRoom()
....{
........myRecorder = GetComponent<Recorder>();

........// only the server can transmit voice
........if (GlobalSettings.iAmServer)
........{
............myRecorder.Init(PhotonVoiceNetwork.Instance.VoiceClient);
............myRecorder.TransmitEnabled = true;
........}

........base.OnJoinedRoom();
....}
}

(how do you format code in this editor?

)

You have one Recorder that has TransmitEnabled and that is not set up properly with a ViewID.
If the prefab has a Recorder and that recorder is set as PhotonVoiceView.RecorderInUse then no need to set the PhotonVoiceView's PrimaryRecorder or use that PrimaryRecorder feature at all.

Here is how it works:

- each player should have a Recorder.UserData set to a ViewID owned by the player before starting transmission
- then the player can start transmission
- once the transmission is enabled for the first time the recorder needs to be initialized
- Recorder initialization will do -among other things- send voice stream info to everyone inside the room
- when receiving the voice stream info players should link/bind it to a Speaker component using the ViewID obtained from the UserData sent in the voice stream info event

This is done for you using the PhotonVoiceView which locally sets up Recorder or Speaker for the PhotonVoiceNetwork to link the remote Recorder(s) with local Speaker(s).

Hi @Suspensorio,

Thank you for choosing Photon!

The title of this discussion is misleading.
The issue is not about UserId but "UserData" as the error log states:

UserData (null) does not contain PhotonViewId. Remote voice 1/1 not linked

What this error says and what the last screenshot shows is that you are not using the PhotonVoiceView correctly or you are not instantiating a PUN prefab (that has PhotonView attached to it using PhotonNetwork.Instantiate) at all! I think maybe you attached the PhotonVoiceView to a scene object which is not supported by Photon Voice. You need to instantiate a prefab per player as an avatar/character that has a player owned PhotonView and to which you attach a PhotonVoiceView.

Hi @JohnTube, thanks for the answer!

I tried something like that just now, but I got the same error.
There is a prefab with PhotonView, PhotonVoiceView, Recorder, Speaker and AudioSource, hopefully all configured correctly. This prefab is instantiated inside OnJoinedRoom, using PhotonNetwork.Instantiate. A bit later, I set the primary recorder to que one in the instantiated prefab, and try to init the Recorder.

What would be the correct flow to instantiate a player with a PhotonVoiceView? I don't need any mechanics on this player, since they are only viewers or act on the world indirectly, so it can be as simple as needed.

Thanks a lot, @JohnTube! I finally got it working now. And Photon is wonderful, as soon as I got that problem solved and another with TransmitEnabled, everything just work!

I think this kind of information should be on the docs on the website. It's a very specific workflow behind-the-scenes, people implementing Voice should know it as a basic information.
