Hello, I have been using Manjaro for quite some time now, today I have experienced that my audio device (integrated sound card in my Dell Vostro 7500) is not detected anymore. I try to always keep my laptop up to date, whether it is regular updates, or kernel, currently I am on 618, I tried some debugging with AI where we tried to blacklist snd_hda_intel, tried to set sof-hda-dsp model=alc236-dell, however nothing made Manjaro recognize the audio device, I know it works, since if I boot to Windows the speakers and jack work just fine, also I am sure the pipewire is also working since when I connect my bluetooth headphones the audio also works. Any tips?
Welcome to the forum! 
I’m no audio expert — one will undoubtedly be dropping by in a short while 
— but first things first… Since you are dual-booting with that other system, did you disable Fast Startup in Windows, as well as Fast Boot in the UEFI firmware? Also, is Secure Boot disabled?
By default, shutting down Windows does not actually shut it down, but instead, it’ll go in a hybrid sleep mode, whereby parts of the hardware are not released — i.e. properly reset — and remain under control of Windows. If this is the case with your audio circuitry, then the Linux kernel cannot see the device upon booting, and this is why Windows must be properly shut down before booting into GNU/.Linux.
Hello, thank you for the suggestions, yes, the secure boot, fast boot are both disabled, I believe I was struggling exactly with both of these when switching to dual boot, never changed it since, also the audio stopped being recognized very recently (today 10.12.) I noticed there was like 4,3GB of updates that I installed, also I was doing some cleaning before with commands like sudo pacman -Rns $(pacman -Qtdq), enabled fstrim and used rmlint to clean some storage space, I was wondering if I didnt remove some necessary driver piece, but everything seems to be working normal, its just that the audio is not recognized
Well, the audio driver is normally in the kernel itself, so I would suggest switching to another kernel. This Stable Update introduced 6.18 as the new LTS kernel, so perhaps you could try that one. 
sudo mhwd-kernel -i linux618
alright, I am officially dumb, btw I am running the 618 kernel, that was not the issue but apparently installing the packages sof-firmware alsa-ucm-conf was neede, I guess during the cleaning up they were labeled as orphaned? not sure but now its working, thanks for help
