I used Soyntec USB Camera with microphone on a Windows 7 desktop computer. I have Firefox 36.0 and started a Hello conversation. Used my laptop computer with Windows 7 and through Firefox browser joined the conversation. The laptop has built in camera and mic and I grant permission to their use and see their icons. However on the desk top it asks permission only for the camera (not for the mic; perhaps because they are built together). When I grant permission on the top of the screen a camera symbol momentarily appears with a ding sound and disappears. I just see the screen which informs that I need to allow the use of camera and mic. nothing shows either on the desktop or on the laptop computers. Need more information how to setup camera and mic to begin a conversation and detailed step-by-step instructions and screen shots as how a real video conversation would look. I have used CITRIX and GoTOMeetings on this computer.
