If voice chat stops working during a session, first check whether you and your partner have moved beyond proximity range. The walkie-talkies appear automatically when you are too far apart to hear each other directly. Release the transmit control while your partner speaks, then swap turns. If neither player can hear the other, check the selected microphone and the voice-server connection before assuming the puzzle has broken.
Launch-period voice failures have more than one possible cause. Unexpected voice-service maintenance occurred after release, while audio input settings also have a separately documented saving issue. A restart or a setting change is a troubleshooting attempt, not a guaranteed fix for every interruption.
Identify the kind of silence
Guide diagram summarizing the checks above.
Use a short, repeatable exchange instead of continuing a puzzle while guessing whether your partner can hear you. Ask one player to say a distinctive word, stop transmitting completely, and listen for the reply. Repeat in the opposite direction.
| What you observe | What to check first |
|---|---|
| Speech stops when you separate | The change from proximity speech to the walkie-talkie |
| You hear your partner until both of you transmit | Take turns and release the transmit control |
| Only one player cannot be heard | That player's selected input device, volume, mute state, and platform voice settings |
| Both players lose communication and see a voice connection error | The voice-server connection and network conditions |
| The microphone selection changes after leaving settings | Reopen the input menu and check the audio-settings saving issue |
These observations narrow the next step; they do not identify a server outage by themselves. Keep track of whether game movement still works, because losing voice while remaining in the level is different from being disconnected from the session.
Recheck the input without changing several settings at once
- On PC, confirm that the microphone you intend to use is the default input in Windows.
- Select that same microphone in the game's audio settings. Check the input volume in both places.
- Leave the settings menu, reopen it, and confirm that the selection remains correct. Audio input settings are not always saved in the launch build's known-issues list.
- Unplug unnecessary USB devices if several audio devices are competing for selection, then test the intended microphone again.
- Check that neither player has muted or blocked the other. On console, also check that voice communication is allowed by the account's privacy settings.
For an Xbox session, a party can take microphone focus away from the game. Test outside the party if the headset works in the party but remains silent in Tomorrow. Reconnecting the headset is also a documented troubleshooting step.
After each change, repeat the same two-way phrase test. Changing the input, region, headset, and network together makes it difficult to tell which condition affected the result.
Check the connection when the voice service fails
Make sure both players have selected the appropriate in-game region and that their region settings match. On PC, check that Windows is updated and that the system clock uses the correct time and time zone. A clock change helped some launch-day players, but other players reported continued failures, so it should not be described as a universal solution.
Use a stable connection, preferably wired, where practical. Campus, library, and other public networks may restrict the voice service even when ordinary internet access works. If your security software blocks the game, allow the game through the relevant antivirus or firewall rules rather than disabling protection wholesale.
The game and voice connections can fail for different reasons. If the error remains after local checks, record the exact message and whether both players were affected. Unexpected maintenance was acknowledged during launch; that historical incident does not establish the service's current status or prove that your microphone is faulty.
Keep the session usable while you investigate
If you can remain in the game, agree on a temporary communication method with your partner before retrying a puzzle. An external voice call can keep information moving, although it will not reproduce the intended proximity and radio presentation. It also does not repair the in-game voice connection.
Do not repeatedly reload a checkpoint just to test a silent microphone. Checkpoints are useful for restoring blocked gameplay, but the available guidance does not establish checkpoint reloads as a voice-chat fix. If you need to leave the session, note your current checkpoint first.
For a persistent report, keep the platform of each player, selected input device, whether nearby speech and distant radio both fail, the error text, and the point at which sound stopped. Those details distinguish an input-selection problem from a radio-use mistake or a service connection failure without promising a fix that has not been verified.
