This looks like an user space configuration problem.
I have placed ALSA card definitions (I think) from LibreELEC on my
system from
https://github.com/LibreELEC/LibreELEC.tv/tree/master/projects/Rockchip/
filesystem/usr/share/alsa/cards
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.
Will do.
FTR: It's now working again for me on a kernel with this patch included:
https://github.com/LibreELEC/LibreELEC.tv/issues/5734#issuecomment-940088156
I have no idea whether this is a proper solution or another
'workaround', but
it's working for me again :)
The patch bellow resolved your issue - alsa-lib configuration fix. But it's
not an universal solution and there may be clashes with other simple-card
drivers in future.
