katana don't recognized

hi,
I installed the last update from volumio, before playing something i do a restart after i played the music from tidal and it worked.
After the second reboot it seems to not recognize the allo katana dac anymore.
when i try to Failed to play the music i get this error: open “alsa” [alsa]; Failed to open ALSA device “hw:1,0”: No such file or directory
I’ve tried selecting the raspi soundcard, reboot and selecting again the dac, do a factory reset but nothing worked.
Alsamixer only recognize the broadcom soundcard (but i don’t now if this can help, maybe katana isn’t reported into that list, i didn’t check before)
Katana’s status led is green so i think that the problem is not hardware releted.
can you please give me a hand?
