Stop sound from replaying in while loop

I am trying to make a sound play continuously if a certain time has passed. Below is my code. However, the sound keeps replaying instead of one continuous sound as it is in a while loop. Putting it outside the while loop will not work as the time is incremented inside the while loop. How do I go about doing this? Please help! I have been stuck at this for 2 days..... This is an issue with my ordering of my coding, so its nothing to do with the sound being played correctly or not.
Thanks!
t = 0;
pahandle = PsychPortAudio('Open', [], 1, 1, 48000, 2);
myBeep = MakeBeep(500, 0.5, 48000);
PsychPortAudio('RunMode', pahandle, 1);
PsychPortAudio('FillBuffer', pahandle, [myBeep; myBeep]);
while t < 20
t = t + 1;
if ~KbCheck && t >= 5
PsychPortAudio('Start', pahandle, 0, 0, 1);
elseif KbCheck
PsychPortAudio('Stop', pahandle, 1, 1);
break
elseif t > 20
PsychPortAudio('Stop', pahandle, 1, 1);
break
end
end
PsychPortAudio('Close', pahandle);

At t == 6 your condition
if ~KbCheck && t >= 5
is going to be true, so you are going to re-issue the start.
