Still, seems easy enough to do basic sounds in linux by shelling the
beep command....


program soundcheck;

uses Process;

var s : ansistring;

begin
   RunCommand ('beep',['-f','100','-l','900'],s);
end.


Fisrt number is frequency, 2nd is length in Ms.
Need to have 'beep' installed, and possibly need to do

sudo modprobe pcspkr
