This patch will set a proper maximum bytes for the buffer, which is: channels * bytes per sample * maximum periods * maximum bytes per period.
It also sets the minimum periods to 6, a value chosen from testing, with a minimum of 6 periods the system has good time to fill in new audio data without skipping.
