My audio card is a SPDIF digital transport compatible with hifiberry-digi-pro, displayed as:
hw:0,0 : sndrpihifiberry HiFiBerry Digi+ Pro HiFi wm8804-spdif-0
(it's dtoverlay is not necessary entered in /boot/config.txt)

My interest is to support native 44.1khz on raspotify and select, if possible hw:0,0 instead of dmix

DietPi v8.19.1 : 12:52 - mar 04/07/23 (debian)
Device model : RPi 4 Model B (aarch64)
6.1.21-v8+ kernel

nothing relevant on journalctl -u raspotify -b
mpd service and upnprender are disabled, nothing is using the soundcard
hifiberry-digi-pro works well before raspotify with mpd and upnprenderer enabled

thanks for support

Is it muted?

I hadn't tested it with music playback, just 'librespot -d ?' output idle.
Now it's working ok, according to my dac, input is 44.1Khz.

This what 'librespot -d ? says on playback: (Idle is same as before)
