Specify the buffer size as itself instead of the period count

Certain backends don't need a buffer size to be a strict multiple of the period
count, which allows a little more flexibility. The period/update size simply
acts as the minimum request, which helps control CPU load by determining how
often parameter and other pre-mixing updates are processed.
