bytcr-rt5651: no soundcards found

Hi, I'm running Debian testing with kernel 4.14 and using your files from this repository as stated in the README for bytcr-rt5651. My machine is based on Atom x5-Z8350, specifically this one https://www.amazon.com//dp/B071WBN8Q2.

aplay -l doesn't show the soundcard:

# aplay -l
aplay: device_list:270: no soundcards found...

First thing that I see in dmesg is:

[    5.591880] bytcr_rt5651 bytcr_rt5651: ASoC: CODEC DAI rt5651-aif1 not registered
[    5.591900] bytcr_rt5651 bytcr_rt5651: devm_snd_soc_register_card failed -517

I already blacklisted the module for HDMI audio support snd-hdmi-lpe-audio, as I found somewhere that it was not supported and might cause trouble. Don't know if it's actually like this.

By looking at the DSDT, it seems that it's actually a rt5651:

# grep -A5 -B5 5651 dsdt.dsl 
            }

And, as I saw you asking for similar commands in bugzilla's issues:

# cat /sys/bus/acpi/devices/10EC56
10EC5640:00/ 10EC5651:00/ 10EC5651:01/ 10EC5651:02/
# cat /sys/bus/acpi/devices/10EC56*/status
0
0
15
0

Is there anything else I can provide for further debugging?

Thanks,
