/** Sound Relay Client<br>
    Connects to given host and port via TCP and receives
    audio data.  This data is then played on some sort of audio
    output line.
    <br>
    <br>
    It works for me, but is hacked togather.  I'm probably not selecting
    the audio line in the right way.  I'm not supporting changing the sampling rate
    or any of the other easily changed items.
