I am trying to excute the following lines with MATLAB app designer
[x, fs] = audioread('wave.wav');
app.freq = 2 * fs;
player = audioplayer(x, app.freq);
play(player);
but no sound is produced. However, when I copy the above lines along with those lines,
restoredefaultpath
rehash toolboxcache
savepath
it sounds in the command window but not in the app designer.
How can I fix this issue? - TIA

I have attached one demo minimum working example.
Have a look. It might help you fix the issue.
Also, if possible provide the full path of the sound file when reading it with audioread()

Then invoke play(app.player)
[filename, pathname]=uigetfile({'*.wav'},'File Selector');
fullpathname = fullfile(pathname, filename);
try
[app.x,app.fs] = audioread(fullpathname);
catch
return
end
app.wavFolderAvailableLamp.Color = 'g';
app.freq = 2 * app.fs;
app.player = audioplayer(app.x, app.freq); % Here app.player is a public property variable
play(app.player);

@Adham Elkhouly I think, if you use sound(app.x, app.freq), then the audio clip will keep on playing even if you close the app window.
Whereas, using the below code, will stop the sound as soon as you close the app window.
app.player = audioplayer(app.x, app.freq);
play(app.player);
