The indenting doesn't matter (just for readibility).
No need of func, no need of continue statement, it will continue anyway.
Code:
#! /bin/bash
while true
do
    if tcpdump -s 700 -t -n -N -X src 67.11.11.11 | grep -E "Miami|Austin|Chicago|Reno"
    then
        echo " found at " $(date)
        play sound.wav
    fi
done

WAVESURFER(1)						      General Commands Manual						     WAVESURFER(1)

NAME

       wavesurfer - soundfile editor

SYNOPSIS

       wavesurfer [options] soundfile

DESCRIPTION

       Wavesurfer  is  a  tool	for sound visualization and manipulation. It can be used as a stand-alone tool for a wide range of tasks in speech
       research and education. Typical applications are speech/sound analysis and sound annotation/transcription.

       The documentation for wavesurfer can be accessed online via www.speech.kth.se/wavesurfer or through the wavesurfer help menu.

OPTIONS

       WaveSurfer recognizes the following command line switches

       -play

       start playing as soon as the sound is loaded.

       -config configuration

       use the configuration and do not query the user for one. WaveSurfer uses the  first  matching  configuration  of  the  available.  If  none
       matches, a wavebar will be displayed.

       -master filename

       when loading several sound files at once, specify which sound's wavebar will control the rest. For example, wavesurfer.tcl -config Waveform
       -master ex1.wav ex1.wav ex2.wav, will make the first sound's wavebar control the second one as well. Same function can be had  by  choosing
       View | Master Widget | ex1.wav.

       -mlf filename

       search  the specified HTK Master Label File (only for HTK format transcription panes). Several options can be specified and they will apply
       to the corresponding transcription pane counting from the top.
