USB Headsets: No Transmit on Mac 10.4.10

Answer

The following applies only to Macintosh computers running Mac OS X 10.4.10.

  • If you experience no transmit (i.e. the mic doesn't seem to work), please try the following:
  • Make sure your Plantronics microphone is plugged into an open USB port on your computer.
  • Launch "Audio MIDI Setup.app." (You will find this application in Applications> Utilities.)
  • In System Settings, select "Plantronics Headset" as the default input.
  • In "Properties For:" select "Plantronics Headset."
  • In the bottom right area of the window, uncheck "Mute."
