What setup-vivox-voice-chat does

The skill covers the com.unity.services.vivox package at 16.4.0 and above. It spells out an init order you should not shuffle: UnityServices.InitializeAsync() first, then sign-in through AuthenticationService, then VivoxService.Instance.InitializeAsync(), and only after that LoginAsync(). Skip a step or reorder them and you get silent failures or cryptic errors.

Channel work gets its own section: group channels for party and lobby, an echo channel to test your own audio, and positional channels that drive 3D audio from a transform. Text messaging is split between channel broadcasts and direct messages, with a table of events to subscribe to before each call. One thing to keep in mind: VivoxService.Instance is a persistent singleton, so unsubscribe in OnDestroy and OnDisable — handlers on destroyed MonoBehaviours double-fire and throw NREs on scene reload.

Vivox 16 dropped the old Client.Instance and ILoginSession model, so code built on those calls will not compile. Older samples you find online need rewriting. Reference files for init, channels, events and troubleshooting are pulled in on demand.

What it helps with

stand up voice chat in a Unity project on Vivox
handle microphone permissions on Android and iOS
build positional audio that follows a player transform
separate team, lobby and direct message channels
subscribe to channel events and clean them up properly

Example prompts for the agent

wire up Vivox in this scene and sign in anonymously
add a positional channel for the squad and a group channel for the lobby
let players send direct messages to each other
