DESCRIPTION="Want to use your Headset under Linux or Mac OS X, but you shout while talking
because there is no support for sidetone? With sidetone, sometimes also called loopback,
you can hear your own voice while talking. This differs from a simple loopback via
PulseAudio as you won't have any disturbing latency."
