Issue with audiorecorder, Audiowrite, audioread, play and recordblobking

[Cleyderman Guerrero]

*Hello Team,

I have an issue with my script. I want to record an audio, graph it, save
and play it. This is my script:*

clear all
close all
clc

s=5;
fs=500000;
r = audiorecorder(8000,16,1); 
disp('please speak')
recordblocking (r,s);
play(r);
y = getaudiodata(r);
subplot(2,1,1);plot(y,'r');
[a,b]=size(y);
a=a-1;
t=[0:inv(fs):(a/fs)]; 
aux=input('push any key to continue');
clc

audiowrite('C:\Users\test\Matlab\soundTest1.wav',y,8000);
aux=input('push any key to continue');
[y2,fs]=audioread('C:\Users\test\Matlab\soundTest1.wav');
sound(y2,8000);

*The above worked fine in Matlab, but in Octave don't work. This is the
error when executing the script:*
