Исправление crypt, (текущая версия) :
а как это можно выяснить минимальные зарежки? есть какой-то код? у меня, ес-но, никаких гитар нет, чтобы гнать звук, а главное, всеравно нужно понимать, как это тюнить.
во FreeBSD довольно большой набор тюнинга через sysctl
в том числе смотри https://man.freebsd.org/cgi/man.cgi?query=snd&sektion=4
hw.snd.feeder_rate_round
Sample rate rounding threshold, to avoid large prime division at
the cost of accuracy. All requested sample rates will be rounded
to the nearest threshold value. Possible values range between 0
(disabled) and 500. Default is 25.
hw.snd.latency
Configure the buffering latency. Only affects applications that
do not explicitly request blocksize / fragments. This tunable
provides finer granularity than the hw.snd.latency_profile tun-
able. Possible values range between 0 (lowest latency) and 10
(highest latency).
hw.snd.latency_profile
Define sets of buffering latency conversion tables for the
hw.snd.latency tunable. A value of 0 will use a low and aggres-
sive latency profile which can result in possible underruns if
the application cannot keep up with a rapid irq rate, especially
during high workload. The default value is 1, which is consid-
ered a moderate/safe latency profile.
