For the voicemail page, was getting frustrated having to use a darn quicktime plugin to play audio in-page. Here you go:
$( document ).ready(function() {
$('#vmail_table tr').each(function() {
row = $(this);
var link = $(this).find('td:eq(8) a').attr('href');
var img = $(this).find('td:eq(7) a').first();
img.removeAttr('onclick');
img.click(function() {
//delete any existing rows
$('.playback_row').remove();
//insert playback row
row.after('<tr class="playback_row"><td colspan="9"><audio controls id="audio_player"><source src="' + link + '" type="audio/wav"></audio></td></tr>');
$('#audio_player')[0].play();
});
});
});
