failed to import acp5x use case configuration -2

[DocMAX]

docmax@steamdeck: ~ $ ALSA_CONFIG_UCM=/usr/share/alsa/ucm2/ alsaucm -c acp5x set _verb HiFi
ALSA lib main.c:1541:(snd_use_case_mgr_open) error: failed to import acp5x use case configuration -2
alsaucm: error failed to open sound card acp5x: No such file or directory

Why does it fail? I have the following directory set up:

/usr/share/alsa/ucm2/conf.d/acp5x/HiFi.conf
/usr/share/alsa/ucm2/conf.d/acp5x/acp5x.conf

Try alsaucm -c hw:acp5x (you may check the card string identifier using aplay -l - it's the string right after card <no>: prefix).

Thanks, its the same:

docmax@steamdeck: ~ $ alsaucm -c hw:acp5x set _verb HiFi
ALSA lib main.c:1541:(snd_use_case_mgr_open) error: failed to import hw:acp5x use case configuration -2
alsaucm: error failed to open sound card hw:acp5x: No such file or directory

docmax@steamdeck: ~ $ aplay -l

Nevermind. I fixed this creating a symlink to the UCM2 root.
-> /usr/share/alsa/ucm2/Cirrus/CS35L41
