Volumio 3 on RPi ext. DAC Topping D50s sound issue

Hello guys
looking for help …I’m almost sure that I’m doing something wrong but can’t figure out what:-) Have Topping D50s DAC connected to Rpi running Volumio 3 on USB output. The DAC is recognized by Volumio and set as output device. But Display on Volumio show FlAC file 192/24 but display on Topping PCM only doesn’t matter if i’m playing, MP3, DSD, Flac…Any idea what’s wrong?

Thank you
