No internal device trough PA with alsa-lib 1.2.4

I've always used alsa and PA as it comes with kde since then, so I can't really tell if it's a bug or a config error.. But nothing i found on here or anywhere else seems to match my situation nor fixes it.

Everything seemed to work perfectly before update (or at least, I never had any problem). After updating alsa to 1.2.4, no output device appear in pavucontrol anymore. However, my bluetooth headset does and gets sound properly when I connects it.

Also, playing wave file trough aplay like so works aplay --device sysdefault:CARD=PCH sample.wav

I narowed the problem down to alsa-lib. All of the other alsa packages can be updated to latest version without causing any issue.

i can reproduce the issue consistantly:

downgrade alsa-lib to 1.2.3.2
restart pulseaudio or reboot
internal device appears in pavucontrol and sound works perfectly
update alsa-lib back to 1.2.4
restart pulseaudio or reboot
no devices in pavucontrol and obviously no sound

Here are all the informations I already gathered
