The latest version does not load audio and speaker devices for making calls over Gmail/Gvoice/Hangouts. When call is initiated, no dialing can be heard. If user clicks on "settings" icon, speak and audio device fields are empty. Selection drop-down does not work. Steps: -sign into gmail -click "red" call button at bottom left -dial # and hit enter -status--> calling (BUT no audio, speaker, mic ... devices are not loading) Windows 7 Pro. Went back to version 18.104.22.168 and it works.
