Buggy sound at beggining of track on LineageOS 14.1 based on 7.1.2

[blores]

Buggy sound at beggining of new track. Possibly happens after few tracks already played.
Sound fixes when unlock-lock screen is done.
Tracks are read from micro sd card (lots of folders and mp3s), other players play fine.
Buggy-choopy sound might be slow buffer. Music(sound) is distorted with small silence pauses (about 300ms long)

Importance: make SMP unusable, because need to hit lock unlock screen every time.

device: Xiaomi Hm 1s with aux jack connected. Strange, but now I'm not able to replicate it without aux cable connected. version SMP1.2 from F-droid

if you need more info ask

Does the problem occurs when using standard android music player ?
