Apparently, the alsa-lib configuration is used in this case.
It seems that there are four sound cards (Analog/HDMI/I2S/SPDIF) created for your hardware. The alsa-lib configuration is a bit weird - an obfuscation for the simple-card driver use. The simple way to resolve this is to create a proper UCM configuration.
If you need further assistance, create an issue for alsa-lib or alsa-ucm-conf on github and with an output from the 'alsa-info.sh' script.
