Load the data using csvread/xlsread/readtable
Pick the required column and use sound

This is the code i used. i am getting error as defined function or variable 'y'.
T=readtable('2khz.csv');
% ^^^^^^^^^------ your csv filename
p=T{:,1};
q=T{:,2};
r=T{:,3};
s=T{:,4};
t=T{:,5};
u=T{:,6};
save('mymat.mat','p','q','r','s','t','u')
load mymat.mat
filename='mymat.wav';
Fs=6000;
audiowrite('mymat.wav',y,Fs);
clear y Fs
[y,Fs]=audioread(filename);
sound(y,Fs);

Using numbered variables is never a good idea.
Do this instead:
T=readtable('2khz.csv');
A = table2array(T(:,3:8));
Then, in the save call, add ‘Fs’:
Fs=6000;
save('mymat.mat','Fs','A')
You can then use audiowrite with the matrix:
audiowrite('mymat.wav',A,Fs);
You can import all your data with audioread, however sound will only work with at most two channels:
[y,Fs]=audioread('mymat.wav');
sound(y(:,3:4),Fs);
for example.
