--- Comment #19 from Raymond <superquad.vortex2 at gmail.com> ---
for alsa-time-test.c

dev = argc > 1 ? argv[1] : "front:0";
    cap = argc > 2 ? atoi(argv[2]) : 0;
    fillrate = argc > 3 ? atoi(argv[3]) : 1;


there are three parameter which allow you to change 

device
capture or playback
fillrate


most sound cards cannot use default fill rate 1 

for hda-intel, the hw_ptr increase by 16/32 frames  for each dma transfer, 
fill rate can be lower than the period size
