So I had this problem before , I couldn`t use teamspeak unless I had a call open in Skype. Now I have this problem again. Just Skype works when I try to talk in Steam or Ts it won`t work. Again it only works if I have a call open in Skype. I have searched for a solution and found this : According to the TS3 Forums I need to go : Skype Tools --> Options --> Sound and uncheck Automatically adjust microphone settings . The problem is I can`t find those options on Modern Windows ( Windows 8 Skype ) . When I had this problem it got fixed 2 months later but I don`t know what I did and I don`t want to wait that long.
