After 3 months of playing, my voice chat stopped working. When I press "U" to speak, the microphone icon and my name appears for me, but only for me, my team cannot hear me and I cannot hear my team.

Everything was working normaly, and it happened.

I tried the VoIP troubleshooting FAQ, check files in STEAM and re-install my game, but it doesn't work.

In other games, discord, it's ok, the problem is only in R6.

It is impossible to play without communication.

Hey,

Sorry to hear you are having some issues with the mic in-game.

There are 2 suggestions below you can try to resolve this:

1) Please make sure the microphone is set as “Default Communications Device” in the audio settings of Windows to control your communication device.

2) Go to C:\Users\CurrentUser\Documents\My Games\Rainbow Six - Siege\UplayID
Go to GameSettings.ini
Go to Audio
Change "VoiceChatCaptureMode=" to a 1 on the variable.

Thanks for trying that. I've found a few more steps to try:

1. Open your “File Explorer” and click on “Control Panel”. Then click on “Hardware and Sound” and then click on “Sound”.
2. Click on the “Recording” tab and then select your microphone (i.e. “Headset mic”, “Internal mic”, etc.) and click "Properties".
3. Click the "Advanced" tab. Click on the check mark in the box next to "Allow applications to take exclusive control of this device" to remove the check mark from the box. Then click "Apply".
