A technique includes providing a sidetone path to generate sidetone
content in response to audio data and disabling at least part of the
sidetone path during an active mode of a radio. The technique includes
storing the sidetone content in an outgoing audio buffer that is
operational during the active mode of the radio and establishing a delay
in the sidetone path to prevent the outgoing audio buffer from being
depleted of the sidetone content during the active mode of the radio.
