.. *slave.diff contains 'slave' implementation, a tiny layer to reduce
(playback / locking) contention / latency between hardware interrupt
delivery and userland io. If you experiencing random 'pops' or 'clicks',
it is probably worth a try.

'Buzz'ing or continuous stuttering/crackling is another issue, mostly
related to non-PREEMPTION kernel or PCI latency timing issue (which is
why you get hw.snd.pcm0.latency_timer on es137x).
