Sound not working on vanilla kernel-5.2.2 from https://www.kernel.org

I compiled my own kernel(5.2.2) from https://www.kernel.org. You know, just to get even minimal arch but when I boot into it, sound doesn't work.
Output of

dmesg | grep snd

(cuz I think it's relevant) :

while on the arch default kernel, it's :

.
Full dmesg for my kernel : https://pastebin.com/jYkBu9EK , arch default kernel : https://pastebin.com/Hu7h6Hxp

Configuration for my kernel : https://pastebin.com/5bn0gjyk

I was on gentoo before arch and I've about 6 months worth of  experience compiling kernels. Everything worked fine under gentoo with the exact same configuration(although last version I tried was 4.19, so options not available till then weren't in the config).

Any help/suggestion is appreciated. Thanks in advance!

If you boot into the linux package from [core] does sound work?

You provided the dmesg from a boot with the linux package but it is still unclear to me if the kernel provided by the linux package provides working sound.

Re: Sound not working on vanilla kernel-5.2.2 from https://www.kernel.org

How do you determine that sound doesn't work? It looks like the main card is initialized properly, there's just some second (dummy?) generic device initialized. What do you get for

aplay -lL
speaker-test -Dhw:0,0 -c2
sudo fuser -v /dev/snd/*
