If this is the output of wavread, then see if you have two channels in y
[y,fs] = wavread(filename);
If y is two-channels, Nx2, then just plot one:
y = y(:,1);
dt = 1/fs;
t = 0:dt:(length(y)*dt)-dt;
plot(t,y); xlabel('Seconds'); ylabel('Amplitude');
figure
plot(psd(spectrum.periodogram,y,'Fs',fs,'NFFT',length(y)));

when you have stereo audio, you got two channels. if you can, it's easier to work with one
