[Solved] Asus Dark Hero (X570) Line-Out Sound delay (Matisse)

I've just bought ASUS Dark Hero and I am disappointed by the sound - it is emitted with a delay of like 0.5-1 second when connected to the Line-Out socket of the motherboard.
I have monitors connected to my videocard via displayport and sound goes there without any delay.
What is surprising is that the sound driver which works with the sound is called "snd_audio_intel".

Starship/Matisse HD Audio Controller.

I have no idea where to look for a solution. Does anyone have any idea?

UPD:

Apparently fixed by changing the buffer sizes: (the Laggy Sound section):

/etc/pulse/daemon.conf

default-fragments = 5
default-fragment-size-msec = 2

I had only these and commented out:

; default-fragments = 4
; default-fragment-size-msec = 25
