Hi John Hock,
You may refer to the link below to check what is the minimum Hz can be play in your system or copy the code to test your system.
foo = rand(1,1000);
for r = 80:8000; try sound(foo,r); fprintf('\nOk at %d!\n', r); break; catch ME; if mod(r,100)==0; fprintf('%d...', r); end; end; end
In my system, it allow 1000 minimum to play audio.
