I am running a script for an experiment that sends triggers through a parallel port, followed by playing a sound, and so on. This happens 60 times but it is crashing on the 48th-50th run every time.

for i=1:cfg.ncycles
    disp([num2str(i) '  on']);
    putvalue(dio,2);
     wait(0.01);
    putvalue(dio,0);
   sound(y2,Fs2);
   wait(cfg.ontime);
    disp('off');
    putvalue(dio,4);
    wait(0.01);
    putvalue(dio,0);
    sound(y3,Fs3);
   wait(cfg.offtime);
end;

The error I get is:

Error using sound (line 76)
Unexpected exception in plug-in:
'boost::thread_resource_error'
 Error in brushscs (line 68)
 sound(y3,Fs3);

The version of MATLAB is 2014a on a 32bit computer. I do not get the same error on 2017a on a 64bit PC but need to run it on the 32bit version for practical reasons.

Has anyone encountered this error in the same or a similar situation?
