Playing but no sound

Volumio Information

Volumio Version: 2.917
Hardware: RPi4B
DAC: Gustard X16

Play Tidal from andriod smaetphone through mconnect (uPnP). Time is running but no sound. Try to play from music library but found music library disappeared. Rescan or update didn’t help. USB DAC cannot be seen in the drop down menu but no ALSA error (I usually got ALSA error if USB DAC cannot be seen). Power cycle USB DAC didn’t help. Restart volumio (volumio vrestart in SSH) didn’t help. Unplug the USB cable and plug again made everything back to normal.
