Right sorry to hear that.

Was it my config that borked bootup?

Okay the problem was the nvme option. Somehow it got enabled as module. Anyway here's the present setup.

Something tells me this lack of volume control is a bug.

Maybe I should upgrade gmome-control-centre?

Anything not seen is built into kernel.

Any soundcore module?

Built in. Could 'modulize' it. Will look.

Would this make any s difference

Yeah it could be a timing thing. IMHO you need snd_hda_intel to settle....with its codec and then they are dependencies of snd and soundcore

its easier to see in post 12

to save wasting time....have all sound stuff modules please...ok?

find /lib/modules -name soundcore.ko gives:

/lib/modules/5.15.13/kernel/sound/soundcore.ko

hmmm I wonder if you are missing an alias setup.....but I do not use LFS so may have to slink away.

eg
Now allegedly on a LFS the alias set up is in /etc/modprobe.conf

I got this from post 5 this link
https://www.linuxquestions.org/quest...1/#post1455758
but the other setup of defining alias snd-card-0 would be one of 2 options
snd-hda-intel or snd-snd-soc......maybe try snd-hda-intel first

2) I have no such entries on a Debian system. I think I am using udev with files from /etc/alsa dir

this is probably my last post on this theme as I do not use LFS

are you a member of audio and video groups

and there is mention of udev issues as per
