OK but, overwrite the buffer with silence depend of software, no? Why 
the buffer is not overwrite with silence with this pcm setup? It is as 
documentation.

PCM:

ALSA <-> PulseAudio PCM I/O Plugin
Its setup is:
   stream       : PLAYBACK
   access       : RW_INTERLEAVED
   format       : S16_LE
   subformat    : STD
   channels     : 1
   rate         : 48000
   exact rate   : 48000 (48000/1)
   msbits       : 16
   buffer_size  : 720
   period_size  : 240
   period_time  : 5000
   tstamp_mode  : NONE
   period_step  : 1
   avail_min    : 240
   period_event : 0
   start_threshold  : 240
   stop_threshold   : 720
   silence_threshold: 0
   silence_size : 6485183463413514240
   boundary     : 6485183463413514240
