PUBG Mic Not Working: Team Voice, T Key, Input Device, and Windows Fix

Last updated: July 18, 2026

When your PUBG mic is not working, do not immediately assume the headset is broken. PUBG voice chat depends on the in-game voice mode, channel, push-to-talk key, Windows microphone permissions, the default input device, Steam voice settings, and sometimes network or CPU load.

The most common confusing case is this: Discord works, but PUBG does not. That can happen when Discord remembers the correct microphone while Windows, Steam, or PUBG uses a different input device. This guide separates microphone input problems from team voice output problems so you can fix the right setting first.

Identify the Exact PUBG Voice Chat Problem

Start by checking whether the problem is your microphone, your output device, one muted teammate, or a broader voice-channel connection problem. This prevents unnecessary driver changes and reinstalling PUBG when the real issue is only a channel or input device setting.

1. Check PUBG Voice Mode, Channel, and Volume

PUBG’s official voice-chat guidance points users to Settings → Sound → Voice Chat, where the talk button, channel settings, and voice volume are controlled. Start here before changing Steam or Windows settings.

1. Launch PUBG.
2. Open Settings.
3. Go to Sound → Voice Chat.
4. Make sure voice input mode is not muted.
5. For diagnosis, select Push to Talk.
6. Set the voice-chat channel to the team-only channel when testing with squadmates.
7. Raise voice-chat volume above zero.
8. Check whether the mic feedback or input indicator reacts while speaking.

2. Confirm the T Key and Push-to-Talk Binding

On PC, the default PUBG push-to-talk key is commonly T. If you use push-to-talk, the key must be held while speaking. A short tap will not transmit a sentence.

1. Set voice input mode to Push to Talk.
2. Open keybind settings.
3. Confirm the current voice-chat talk key.
4. Hold the assigned key while speaking.
5. Watch for the microphone icon or input feedback.
6. Check whether the key is duplicated by another game action or blocked by keyboard software.
7. Test another simple key temporarily if T does not register.

3. Test the Microphone in Windows

Windows must receive a clear microphone signal before PUBG can use it. This test also helps you find whether the selected input device is your actual headset mic, webcam mic, laptop mic, or virtual audio device.

1. Open Settings → System → Sound.
2. Under Input, select the microphone you actually use.
3. Start the microphone test.
4. Speak at your normal in-game volume.
5. Confirm that the input meter moves.
6. Play back the sample if Windows offers a sample recording.
7. If the level is too low, raise input volume gradually.

4. Allow Windows Microphone Access

Windows can block desktop apps from using the microphone even when the device is connected. PUBG and Steam are desktop apps, so the desktop-app permission must be enabled.

• Turn on Microphone access.
• Turn on Let apps access your microphone.
• Turn on Let desktop apps access your microphone.
• Close Steam and PUBG completely after changing permissions.
• Relaunch Steam, then PUBG.

5. Set the Default Input and Communication Device

If Discord works but PUBG does not, PUBG may be following the Windows default communication device while Discord uses a manually selected mic. Set the correct microphone in Windows before launching the game.

1. Open Settings → System → Sound.
2. Choose your headset microphone under Input.
3. Open More sound settings.
4. Go to the Recording tab.
5. Right-click the microphone you use.
6. Select Set as Default Device.
7. Select Set as Default Communication Device.
8. Go to the Playback tab and set your headset as the default output device.
9. Restart Steam and PUBG.

6. Use Steam Voice Test as a Diagnostic Step

Steam’s microphone test helps confirm whether Steam sees the correct microphone. It does not replace PUBG’s in-game voice settings, but it is useful when Discord works and PUBG does not.

1. Open Steam.
2. Open Friends & Chat.
3. Open the voice settings area.
4. Select the correct input device.
5. Start the microphone test.
6. If Steam works but PUBG does not, return to PUBG voice mode, channel, and keybind settings.
7. If Steam also fails, fix Windows permissions, default input, connection, or driver first.

7. Team Voice Not Audible

If your microphone works but you cannot hear teammates, focus on output and mute settings rather than microphone input.

• Make sure PUBG voice-chat volume is above zero.
• Set the channel to the correct team or squad channel.
• Open the team management screen and check individual mute status.
• Open Windows Volume Mixer and check PUBG or TslGame app volume.
• Confirm Windows output is your headset, not HDMI monitor audio.
• Ask whether the affected teammate has their own microphone muted.

8. Voice Chat Cuts Out Mid-Game

Voice that works at the lobby but drops during a match can be caused by device switching, high CPU load, bandwidth usage, virtual audio tools, or unstable wireless devices.

1. Check whether a USB or Bluetooth device was reconnected during the session.
2. Confirm the Windows default input and communication device did not change.
3. Close PUBG.
4. Reconnect the microphone or headset.
5. Close Discord, Voicemod, virtual audio mixers, OBS, and browser voice tabs for testing.
6. Open Task Manager and check CPU, memory, disk, and network usage.
7. Pause downloads, streaming, cloud sync, and uploads.
8. Launch PUBG again and test voice chat in a new match or training mode.

9. Bluetooth, USB, and Virtual Audio Devices

Bluetooth headset checks

• Confirm the headset microphone is selected as Windows input.
• Remove the Bluetooth device and pair it again.
• Update Windows and the Bluetooth driver.
• Close Discord and PUBG before reconnecting.
• Check whether stereo output and hands-free microphone profiles are separated.
• Compare a wired headset or USB microphone.

USB headset and microphone checks

• Plug the device directly into the PC instead of a USB hub.
• Try another USB port.
• After reconnecting, set the Windows default input again.
• Check the headset control app for mute, noise suppression, and sidetone settings.
• Restart PUBG after changing the device.

Virtual audio and voice changers

Voicemod, virtual audio cable tools, stream mixers, and capture software can add extra input devices. PUBG may choose the virtual device instead of the real microphone. Close them and re-select the correct Windows default input before launching PUBG.

10. CPU, Bandwidth, Firewall, and Network Checks

PUBG Support notes that poor voice quality can be affected by bandwidth and high CPU usage. If the microphone works but voice quality is choppy, check system and network load.

1. Turn off VPNs, proxies, and network accelerators.
2. Pause broadcasting, large downloads, cloud backups, and streaming.
3. Use Ethernet instead of Wi-Fi when possible.
4. Restart the router and the PC.
5. Check Windows Security and third-party antivirus protection history.
6. Allow PUBG or Steam only when an actual official file is blocked.
7. Do not leave firewall or antivirus protection disabled permanently.

11. Verify PUBG Files and Collect Support Information

If Windows, Steam, and PUBG settings look correct but voice chat still fails, check the game installation before reinstalling.

1. Open the Steam Library.
2. Right-click PUBG: BATTLEGROUNDS.
3. Select Properties.
4. Open Installed Files.
5. Select Verify integrity of game files.
6. Wait for the scan and any replacement download to finish.
7. Restart Steam and the PC.
8. Open PUBG and recheck voice settings.
