How can I sound two signals without them overlapping?

Basically I've got two signals I want to sound using the sound(x,Fs) function. Is there any way that I can have the second sound() wait until the first one has finished before playing?

y=audioplayer(S1,Fs);
playblocking(y); % Same as play, but does not return control until playback completes.
sound(S2,Fs); % Play Second Sound

See if this illustration does what you want:
Fs = 8192; % Sampling Frequency
Len = 2.5; % Length Of Sound (s)
t = linspace(0, 100*pi, fix(Len*Fs)); % Length = 2.5s
S1 = sin(t) + sin(5*t) + sin(15*t);
S2 = sin(15*t) + sin(21*t) + sin(31*t);
soundsc(S1,Fs) % Play First Sound
pause(2.5) % Wait For First Sound To Finish
soundsc(S2,Fs) % Play Second Sound

You can call sound twice or you can combine the signals. Here's both methods:
tr = load('train');
la = load('laughter');
% play train:
sound(tr.y,tr.Fs)
% then play laughter:
sound(la.y,la.Fs)
% Or, combine arrays:
combined = [tr.y;la.y];
% wait 1.2 seconds:
pause(1.2)
sound(combined,la.Fs)
The pause command is optional--it insets time after the sound before it finishes playing.

The first example actually does not work in Matlab 2019b. The sounds are played at the same time (at least they are on my system in Windows 10). Good idea about just combining the vectors though. Seems like there should be another way, for example using pause or something, but I haven't been able to do it.
