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 file 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

I did a test with pcm file and the sound is playing very fast,
snd_pcm_open(&handleSound,"hw:0,0",SND_PCM_STREAM_PLAYBACK,0)
Use "default" as device name. Using "hw" will prevent any automatic sample format/rate conversions.
//snd_pcm_hw_params_set_rate(handleSound,hardwareParam,8000,0);
This shouldn't be commented out, and you should check the return values of all these functions.
