Same here. Yesterday with the same config all fine (1.7.1.1 and Beta). Now the same server but no ingame-sound, no reactions from ear/eye-symbols. Other Servers the same Problem. I became a message with "Wrong Version ..." too. But its all up to date and i haven't change anything since yesterday. Hope there will be a solution soon (I reinstalled DayZ manually and with the Updater too, but no change).
