DSD128 and above files not playing

This is my system setup.

System: RPi 3B+ running Libreelec (Kodi v.18.9) and squeezelite.
LMS: on Synology DS220+
DAC: Hifiberry DAC2 Pro capable of 192kHz/24bit

Current setup can play only DSD64 files, but not DSD128 files. Error messages show "[17:21:21.799898] alsa_open:530 unable to set hw params: Invalid argument"

However, DSD128 files can be played using Kodi's music player. Also, if I use "squeezelite -D" then very faint sound can be heard without error messages.

Any idea? Please help.
