bytcr-5640 on HP X2 10-p030nl not working

[dslul]

Hello, I can't get audio to work in this 2in1.
On Windows, from the device manager, I get this id: ACPI\10EC3276\1. After a search on google, I assumed that it is a rt5640.
After copying the files here https://github.com/plbossart/UCM/tree/master/bytcr-rt5640 audio still doesn't work (and nothing shows up on the audio devices list), however there are some differences in pulseaudio logs.

I attach here the results of pulseaudio -vvv before and after copying the aformentioned files.
In both cases, the pulseaudio command terminates with "Killed", and no daemon is started.

the first order of business is to check if the kernel creates a card. Can you paste the dmesg log somewhere? also send the results of alsa-info.sh I see that we have support for 10EC3276 for cherrytrail but not baytrail, that might the issue.

Thank you for your help. I attach here the results of dmesg, and the output link from alsa-info.sh:

http://www.alsa-project.org/db/?f=2cca1e6e6ca1089912f4cbb89bfc2230a4dbe3ad

dmesg.log

I see that we have support for 10EC3276 for cherrytrail but not
baytrail, that might the issue.

This laptop has the z8350, it should be cherrytrail, did you mean the opposite?

So the kernel tells me a card was created on a cherrytrail platform, and the pulseaudio logs shows devices being used (with a transition between speaker and headset). no smoking gun really. I am not sure how I can help at this point, either you have a pulseaudio configuration issue or your hardware has specific quirks.

Any hints on what I could do next to understand what the problem is? I tried resetting all pulseaudio configurations. How do I know if this hardware has quirks?
Maybe it's not really a 5640? By doing ls /sys/bus/acpi/devices I get these realtek devices:

10EC3276:00
10EC5640:00
10EC5670:00

EDIT: using vlc the audio works, but only with that, no system sounds and no headphones...
