I can hear you, but my mic is muted. It seems that Lou is assigned to Team Speak as a guest who allowed to listen, but not speak. While I am learning things by being that fly on the wall, I is hard to not say Hi when you are welcomed to the chat.
Welcome to JUGs! You should have permissions to speak in TS. If it isn't working, it is most likely an issue with your TS configuration. Check under Tools > Options > Capture > Capture Device. I know my headset took a few tries to get set up correctly between the manufacturere's software, Windows settings & Teamspeak.
