also, on Fedora, the listing for a.wav is as you have indicated.

also, also, recompiled with debugging turned on, here is an output segment

octave:1> A = [1:10; 1:10]/10;
octave:2> wavwrite("a.wav", A);
octave:3> [B, samples_per_sec, bits_per_sample] = wavread("a.wav");

Thanks John,

a.wav:          audio data: 16-bit linear PCM,
    

This looks strange. Can you check with other wave files, if this output
is the expected one?

Here: 
$ file a.wav 
a.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, 10
channels 8000 Hz
