As I suspected, the modules aren't loaded so alsa isn't even running.
Hence your original "open" error(s).
How did you install alsa? Not that I think it is your issue, but it
could be. If you boot with lilo, you need to re-install lilo after
creating a new kernel. Even if it's technically the same version of
your old kernel. Although most distros default to grub these days.
So not likely.
If you compiled from source at least for some modules, you'll need to
reboot to use the new kernel and the new modules. Not really
applicable to sound as you probably didn't change any PCIe or other
internals to gain the functionality.
In the old days if you compiled from source you could insmod
(modprobe) the modules in alsa-driver-???/modules/ until you got the
right order and all of the modules loaded. This is representative of
the errors that you're seeing. You can't load a certain module
because another module wasn't loaded before it. That has those
symbols (functions) that it needs. Which brings things full circle to
alsa isn't properly installed.
Well, I installed alsa by running
$ sudo apt-get install alsa
And technically it was there in the beginning. I could access alsamixer and adjust everything. Now I can't. I was trying to install microphone, so I probably reinstalled alsa and for some reason it doesn't work now :(
I don't really know about those advanced methods. I'm new to this whole stuff :(
$ sudo dpkg -l '*alsa*'
Only pay attention to the ones that start alsa or alsa-. On my debian
setup (similar to ubuntu) I have alsa, alsa-base,
alsa-firmware-loaders, alsa-headers, alsa-source, alsa-tools,
alsa-tools-gui, and alsa-utils. On my system all of those are
installed, except alsa-firmware-loaders, alsa-headers (needed to
compile other things from source against it), and alsa-tools-gui. IMO
you are probably missing alsa-base. This should have entries in
/etc/modprobe.d/alsa* for autoloading your modules (without concerning
yourself about the order of insertion). It could also be that you
haven't run depmod -a, or your distro didn't. Which updates a sort of
list of what modules are related so they can also load when the other
is loaded. IME, alsa is independent of this list and relies on other
things (/etc/modprobe.d/).

Looks like there's some problem with alsa :( How to fix this?
If you haven't solved your issue by now, I guess you're stuck with the
old school ways. Meaning you'll likely have to create a
/etc/modprobe.d/ entry for alsa so it can auto load at boot. Which
might look something like:
...
And 20 years after linux started, we're still configuring sound from
the command line. Be sure to reboot OR try to use the soundcard to
get the modules to auto magically load. They generally load at boot
because your distro will likely try to restore mixer settings. And
therefor try to use your soundcard. (which is or was failing for you)
I made this file: /etc/modprobe.d/alsa_custom.conf and copied this into the file, saved.
Unfortunately after the reboot nothing works :/ I am probably doing something wrong. Should the name be alse_custon.conf?
Like my previous speaker already told: the modules cannot be loaded because other modules are missing. Either you don't have modules installed at all (which most certainly means you have a wrong kernel image running) or the module loader cannot resolve the dependencies. To check if the module directory exists type
$ ls /lib/modules/$(uname -r)
build modules.builtin.bin modules.inputmap modules.softdep
initrd modules.ccwmap modules.isapnpmap modules.symbols
kernel modules.dep modules.ofmap modules.symbols.bin
modules.alias modules.dep.bin modules.order modules.usbmap
modules.alias.bin modules.devname modules.pcimap updates
modules.builtin modules.ieee1394map modules.seriomap
Looks like it exists.
$ sudo depmod -a
$ sudo modprobe snd-hda-intel

Looks like module loader is not willing to cooperate :/ Do you know what's going on?
Thank you all for the replies! Please help!
