Rainbow Six Siege Voice Chat Not Working on Windows 10

If your Rainbow Six Siege voice chat is not working on Windows 10, the fix usually involves checking your in-game voice settings, Windows microphone privacy permissions, and the Ubisoft Connect overlay. This guide walks through each likely cause in order, from the simplest to the most technical, so you can get back to coordinating with your team.

Why Voice Chat Fails in Siege

Rainbow Six Siege uses its own in-game voice system, separate from Discord or other third-party apps. That means the problem can sit in several layers: the game’s audio settings, Windows’ privacy and device settings, the Ubisoft Connect overlay, or even your network’s UDP ports. A single misconfigured setting—like the wrong default microphone in Windows—can block voice entirely, even if other apps work fine.

Step 1: Check In-Game Voice Settings

First, launch Siege and go to Options → Audio. Look for the Voice Chat section and confirm:

• Voice Chat is set to On (not “Push-to-Talk Off” or “Mute All”).
• Voice Chat Input Device is set to your actual microphone, not “Default” if Windows is picking the wrong one.
• Voice Chat Output Device is set to your headset or speakers.
• Voice Chat Record Level is at least 50–80; if it’s too low, teammates won’t hear you.
• Push-to-Talk is bound to a key you can reach easily (default is U for team, Y for all). If you’re using “Voice Activity,” make sure the activation level isn’t set so high that your voice never triggers it.

If you’re in a squad, also check the Party tab in the in-game menu—sometimes you’re in a party channel that’s separate from team chat, and your teammates are in the other one.

Step 2: Verify Windows Microphone Privacy

Windows 10 has a privacy setting that can block apps from using the microphone. Even if the mic works in Discord, Siege might be denied access. To fix this:

1. Press Windows + I to open Settings.
2. Go to Privacy → Microphone.
3. Ensure Allow apps to access your microphone is toggled On.
4. Scroll down and make sure Rainbow Six Siege is allowed. If you don’t see it in the list, click Change and turn on “Microphone access for this device.”
5. Also check Allow desktop apps to access your microphone—this is a separate toggle that often gets overlooked.

After changing these, restart Siege. Windows sometimes doesn’t apply the permission until the app relaunches.

Step 3: Set the Correct Default Microphone in Windows

Siege often uses the Windows default input device. If your headset has multiple microphones (e.g., a built-in laptop mic and a USB headset), the game may pick the wrong one. To set the right default:

1. Right-click the speaker icon in the taskbar and choose Sounds (or Open Sound settings).
2. Go to the Recording tab.
3. Right-click your preferred microphone and select Set as Default Device.
4. Also set it as Default Communication Device—Siege uses the communication device by default.
5. Speak into the mic and watch the green level meter; if it doesn’t move, the mic is muted or broken at the hardware level.

If you’re using a USB headset, try unplugging and re-plugging it, then repeat the steps. For a 3.5mm headset, make sure it’s plugged into the combined headphone/mic jack (often with a headset icon) or use a splitter if your PC has separate jacks.

Step 4: Disable or Re-enable the Ubisoft Connect Overlay

The in-game overlay in Ubisoft Connect can interfere with voice chat. Some players report that disabling the overlay fixes voice; others say enabling it fixes it. Try both:

1. Open Ubisoft Connect (the launcher).
2. Go to Settings → General.
3. Find Enable in-game overlay for supported games and toggle it off.
4. Launch Siege, test voice, then exit and toggle it back on if you need the overlay for friends or challenges.

If that doesn’t help, also check the Voice Chat settings inside the Ubisoft Connect overlay (press Shift+F2 in-game) to ensure the correct mic is selected there as well.

Step 5: Update Audio Drivers and Game Files

Outdated or corrupted audio drivers can cause voice chat to fail even when everything else looks correct. To update:

• Open Device Manager (right-click Start → Device Manager).
• Expand Audio inputs and outputs and Sound, video and game controllers.
• Right-click your microphone and headset, choose Update driver, then Search automatically.
• If no update is found, visit your motherboard or laptop manufacturer’s support page for the latest audio drivers (Realtek, for example).

Also verify the integrity of Siege’s game files:

1. In Ubisoft Connect, go to your Games tab.
2. Right-click Rainbow Six Siege and select Verify files.
3. Wait for the process to finish, then relaunch the game.

Step 6: Check Network and Firewall (UDP Ports)

Siege’s voice chat uses UDP packets. If your router or Windows Firewall blocks those, you’ll hear nothing and others won’t hear you, even though the game runs fine. To fix:

• Make sure Windows Firewall allows Rainbow Six Siege for both Private and Public networks. Go to Control Panel → Windows Defender Firewall → Allow an app or feature through Windows Defender Firewall and check both boxes for Siege.
• If you’re on a strict network (like a college dorm), try enabling UPnP in your router settings or manually forward the ports Ubisoft lists for Siege (commonly UDP 3074 and TCP 80, 443, but check Ubisoft’s official support page for current numbers).
• If you use a VPN, try disabling it—VPNs can interfere with voice chat.

Frequently Asked Questions

Why does my voice chat work in Discord but not in Siege?

Discord uses its own audio system and doesn’t rely on Windows’ “communication device” setting the way Siege does. The most common cause is Windows privacy blocking Siege from the microphone, or the game using a different input device than Discord. Follow the privacy and default device steps above.

Can I use push-to-talk instead of voice activation?

Yes. In Siege’s audio options, set Voice Chat Input Mode to Push-to-Talk and bind a key. This is often more reliable because it avoids the activation level being too sensitive or not sensitive enough. Many players prefer it to avoid background noise.

Why can I hear teammates but they can’t hear me?

This usually points to your microphone input. Check that the correct mic is set as default in Windows, that it’s not muted in the Recording tab, and that the in-game record level is high enough. Also test the mic in another app (like Windows Voice Recorder) to confirm it works at the hardware level.

Does the Ubisoft Connect overlay affect voice chat?

Yes, in some cases. The overlay can sometimes grab the microphone or conflict with the game’s audio. Toggling it off and on has resolved the issue for many players. It’s worth trying even if you don’t use the overlay.

My voice chat worked before a Windows update, now it’s broken. What changed?

Windows updates can reset microphone privacy permissions or change the default audio device. Re-check the privacy settings and the default device in Sound settings. If that doesn’t help, update your audio drivers, as a Windows update may have installed a generic driver that doesn’t fully support your headset.

Is there a way to test my voice chat without bothering teammates?

Yes. Create a custom game or go to the Settings → Audio menu and speak—you’ll see the voice level meter move if the mic is being picked up. You can also join a squad with a friend and ask them to confirm. Some players use the in-game text chat to ask a teammate to test, but a custom game is the safest.
