Follow-up Comment #1:

Look at the help for wavwrite again. It requires that the first argument
contain column vectors only, where each column is a channel. You are using row
vectors, so your snippet here is attempting to create a WAVE file with 8001
channels of 1 sample each. Compare:


dur = 1;
fs = 8000;
tt = 0 : (1/fs) : dur;
xx = sin (2 * pi * 2000 * tt);
wavwrite (xx, fs, "temp.wav"); % Will not work
wavwrite (xx(:), fs, "temp.wav"); % OK


I don't see a bug here, unless you or someone else can demonstrate that Matlab
behaves differently when given a row vector.
