Audio issues with kernel 6.1.0 built with Fenix

Which Khadas SBC do you use?

VIM3L

Which system do you use? Android, Ubuntu, OOWOW or others?

Others, only using u-boot and kernel

Which version of system do you use? Khadas official images, self built images, or others?

Self-built image for Volumio devices

Please describe your issue below:

I successfully built mainline u-boot and kernel (6.1.0) for a Volumio image.
The image boots, I added kvim3l/i2s.dtbo and kvim3l/spdifout.dtbo, but get an audio error, see log file.

aplay -l only gives:

**** List of PLAYBACK Hardware Devices ****
card 0: AMLAUGESOUNDMP1 [AML-AUGESOUND-MP1], device 0: fe.dai-link-0 (*) []
Subdevices: 1/1

No patches were made to u-boot or kernel sources.
Please note that I change the soundcard name during the boot process.
(Using fdt set /sound model "AML-AUGESOUND-MP1" ).
But when I leave the default “KHADAS-VIM3” it does not make a difference.

Post a console log of your issue below:

I cut some irrelevant bits out in order to remain within the given body 32000 character limit

Note the “backend DAIs enabled” error, the userland mixer settings are missing, I obviously have not done yet. In case Khadas knows which ones I need, super. Otherwise I’ll find out some way. But worse, why is there only one card, while there should be hdmi, i2s and spdifout?
