I am trying to make amplitude sweeping of a sine wave and want the output of this wave in the system audio jack.

I have this code working to some extent.

It will make me happy if somebody helps me in this regard.

%%%%%%% Amplitude sweeping %%%%%%%%%%%
clear all;
clc;
Fc = 1000;
Fs = 44100;
dt = 1/Fs;
StopTime = 2;
t = (0:dt:StopTime-dt)';
A = linspace(0, 1, numel(t))';
y = A.*sin(2*pi*Fc*t);
plot(t,y)
grid on
player = audioplayer(y,192000);
play(player);
