it will affect how much work the CPU does. if you set the period size
low, there will be more interrupts and the work that is done every
interrupt will be done more often. so, if you don't care about low
latency, set the period size large as possible and you'll have more
CPU cycles for other things. The defaults that ALSA provides are in
the middle of the range, typically.
