Clemens,
   =

  thanks for your help. Can you explain what function of alsa api I insert =
128kbps value of pcm file? In my example, I'm reading the content of pcm fi=
le and writing directly on sound device, however I don't know the length of=
 buffer that I send to sound device. Can be any length of buffer?
   =

  Thanks,
   =

  Flavio

Use "default" as device name. Using "hw" will prevent any automatic
sample format/rate conversions.

This shouldn't be commented out, and you should check the return
values of all these functions.
