USB DAC and docker image with ALSA

i’m trying to spawn on my laptop a volumio container.
If i use pulseaudio i can listen to music properly but if i throw at it a 192Khz file it is played as 44.1/48Khz, this is also happening on the host machine with deadbeef (if set on pulseaudio device) and i have no idea why.
Instead of using pulseaudio i wanted just alsa so i just piped /dev/snd to the docker and selected my DAC, i can hear the startup sound but no songs can be reproduced properly.

Any help would be great.
This is the image i’m using
