This is what I get in Chromium OS

I have loaded caroline firmware and downloaded alsa.conf sklnau8825adi.conf HiFi.conf, but sudo alsaucm -c sklnau8825adi set _verb HiFi said
ALSA lib /build/amd64-generic/tmp/portage/media-libs/alsa-lib-1.2.1.2-r2/work/alsa-lib-1.2.1.2/src/ucm/parser.c:1513:(get_card_long_name) no soundcards found... ALSA lib /build/amd64-generic/tmp/portage/media-libs/alsa-lib-1.2.1.2-r2/work/alsa-lib-1.2.1.2/src/ucm/main.c:405:(execute_sequence) unable to open ctl device 'hw:sklnau8825adi' ALSA lib /build/amd64-generic/tmp/portage/media-libs/alsa-lib-1.2.1.2-r2/work/alsa-lib-1.2.1.2/src/ucm/main.c:1733:(set_verb_user) error: failed to initialize new use case: HiFi alsaucm: error failed to set _verb=HiFi: No such device

I need your help to figure it out
