Stereo sound doesn't behave as expected

[road,fs]=wavread('road.wav'); % loads “the long and winding road” clip
left=road(:,1);
right=road(:,2);
soundsc(left,fs) % plays left channel as mono
soundsc(right,fs) % plays right channel mono
Why the sound doesn't divided into left channel (Left ear) and right Channel (right ear) ?

Do you mean, when you play soundsc(left,fs) it should only come from the left speaker?

MAybe you need something like this
[road,fs]=wavread('road.wav');
pad=zeros(length(road),1); % blank channel
left=[road(:,1),pad]; % add blank channel so right is silent
right=[pad,road(:,2)]; % add blank channel so left is silent
soundsc(left,fs) % sound only from left
soundsc(right,fs) % sound only from right

When you soundsc() a single column of data, it is sent to both channels. Notice there is no possibility to select whether you are sending to left channel or to right channel when you soundsc()
hint:
soundsc( [left, zeros(size(left))], fs)
