--- Comment #9 from Raymond <superquad.vortex2 at gmail.com> ---
buffe size: 64
Lecture WAVE 'Musique/gillscott.wav' : Signed 16 bit Little Endian, Fréquence
44100 Hz, Stéréo
Hardware PCM card 0 'Odroid-U3' device 0 subdevice 0
Its setup is:
  stream       : PLAYBACK
  access       : RW_INTERLEAVED
  format       : S16_LE
  subformat    : STD
  channels     : 2
  rate         : 44100
  exact rate   : 44100 (44100/1)
  msbits       : 16
  buffer_size  : 128
  period_size  : 64
  period_time  : 1451
  tstamp_mode  : NONE
  period_step  : 1
  avail_min    : 64
  period_event : 0
  start_threshold  : 128
  stop_threshold   : 128
  silence_threshold: 0aplay 
  silence_size : 0
  boundary     : 1073741824
  appl_ptr     : 0
  hw_ptr       : 0


it is strange that aplay still using 128 instead of 64 as buffer size
