Thanks, Tim,
Since I got no boom if I play DSD songs in sequence ( plat all directory ), only got boom when manually select
change, I am not sure they are realted!

attached link is in Chinese, sorry I may be not got "sonic boom" a right naming turn, can't fine English related link.

I try to translate some of them to English,

 at Most cases, ES9018 can use automatic identification,when PCM->DSD, only need use XMOS to handle it,it can do 
switch without noise。but due to DSD128 is equal to PCM352.8 or PCM384,and when ES9018 play song higher than 192K need bypass FIR,here MCU need pass XMOS and introduce DSD/PCM(0: PCM, 1Big GrinSD)、/FIR(0:enanle FIR, 1:bypass FIR) 2 signals to do fast identification and configuration.


Relay switch usually takes 20ms,20ms is enough to let noise happen,so,only depends on Relay is not enough.

    After many trial, through ES9018 register to setup bypass FIR,even setup ES9018 mute,still little sonic boom happen, only "add" relay switch can make it, it's same to CS4398 solve DSD DoP,noixe is happened by PCM 384K.
