Considering playback,
period_size : your sound card will generate interrupt after period_size bytes have been consumed and ALSA core is informed of this, in driver's interrupt handler. Periods : Number of buffer slices , each having period_size bytes. Buffer_size : periods * period_size
Your application should query the driver for the parameters and set accordingly. Below is one good example for writing a alsa application :
