Many times I've wished for a clear list of sample data, perhaps in a simple table given with data type, toolbox, and in which Matlab release(s) you'll find each sample data file. Good documentation of code often requires sample data, and requires confidence that users will be able to follow along with an example, no matter what release of Matlab they're using or what toolboxes they have. I've contacted TMW with this request before and I got a friendly, but non-committal response.
How do I find built in sounds?

I need to load two built in matlab sound files, store them, and concatenate the sounds so they play one immediately followed by the other. I cannot figure out how to even find built in sound files so I am stuck. Can anyone help me figure out the sound file codes?

See Example Audio Data toward the bottom of this list.

To find the location of a file,
which chirp.mat

S(1) = load('gong');
S(2) = load('handel');
sound(S(1).y,S(1).Fs)
sound(S(2).y,S(2).Fs)
And more help: audioread, audiowrite.

if you multiply Gong by Handel, and use a bit rate of 10,000 it sounds like a window breaking.
That might make a nice alarm.
S(1) = load('gong');
S(2) = load('handel');
S(3).y = ((S(2).y(1:length(S(1).y),1)).*(S(1).y));
S(3).Fs = 10000;
sound(S(3).y,S(3).Fs)

Since its launch in R2016a, Audio Toolbox comes with a collection of sample audio files in a combination of diffferent formats, sample rates, number of channels, and durations.
Try the following:
audiosamplesroot = fullfile(matlabroot,"toolbox","audio","samples");
ls(audiosamplesroot)
Get your names into a list
ads = audioDatastore(audiosamplesroot);
aulist = string(ads.Files)
Pick one for inspection
fileId = 1;
Uncomment the following in your MATLAB session for interactive visualization and playback
% audioViewer(aulist(fileId)) %
Or try something more basic
[x, fs] = audioread(aulist(fileId));
t = (1/fs) * (0:length(x)-1);
plot(t,x)
xlim([t(1), t(end)])
xlabel("t (s)")
[~, filename] = fileparts(aulist(fileId));
title(filename)
