Tom Clancy's Rainbow Six Siege

Tom Clancy's Rainbow Six Siege

Everyone is muted
Everyone is muted and I can't unmute my mic is fine; it works in other games. My voice chat is on Ubisoft, and the privacy settings are set to everyone. I'm not comm banned, but I can't talk. Typing infos is starting to get really annoying. Can anyone help? https://imgur.com/a/jWB8EyO
