Details:

When using the following prog:


clear
Fs=44100;
t=10;
x=0:1/Fs:t;
y(:,2)=sin(2*pi*220*x);
y(:,1)=sin(2*pi*440*x);
q=audioplayer(y,Fs,16);
play(q)


If you hit the blue run icon to start the sound, and then press it again and
again, first the sound goes bad and the octave crashes with signal 11 and once
with signal 6.

The time with signal 6  there was an error message about a callback problem. I
did not get it copied down before octave crashed , and then the message was
lost forever.

In summery if you rerun the software before it has finished the first run, it
might crash, some times it doesn't.
