[linux-audio-dev] Linux kernel HZ, audio latency and how to measure?

Hello everyone.... I am kinda interested to study the effect of changing kernel HZ (internal timer frequency) and the audio processing. Since I am a newbie in Linux Audio, I will be glad to receive any comments, especially the constructive ones. Is there any relationship between kernel HZ and audio timing? I imagine that something like audio recording from a Hi Fi will get a benefit from a finer granularity timer frequency, since it can achieve 1ms (or even smaller) resolution. But, if there is relationship between those two, then how to measure it? Do I need to check every delay function and record the requested delay vs the actual delay? Or is there other method? I already searched the archieve looking for the similar question, but I found none. Thank you in advance your help and attention. regards, Mulyadi
