Unhappy All mute after upgrading ALSA

I didn't (maybe still don't) have ALSA loopback so I could record streaming, so I upgraded ALSA following these instructions:

The only part I didn't follow verbatim was the final step:

Allrighty, time to load it. But before that, shut down all audio apps (including firefox). Once done, do this:

sudo alsa force-unload
sudo modprobe snd-whatever-module-you-need
sudo modprobe snd-aloop
I was unsure about "snd-whatever-module-you-need" so I decided to reboot.

When KDE was just about to kick in, I saw a lot of new text I had never seen before scroll past very, very fast. Then it stopped and I could see it had something to with ALSA, but I couldn't really read anything. KDE started and... now I have no sound.

I checked kmixer, it looks normal. It doesn't seem to be mute.

I ran alsamixer in the command line, it doesn't seem to be mute either.

I ran Kcontrol and checked the audio section, couldn't figure anything out.

Here is the output of lsmod BEFORE the upgrade:

$luc> lsmod | grep snd                            
snd_hda_intel         434100  6

snd_seq_dummy          10756  0
snd_seq_oss            37760  0

soundcore              15200  2 snd
snd_page_alloc         16904  2 snd_hda_intel,snd_pcm
Here is the output of lsmod AFTER the upgrade:

$luc> lsmod | grep snd                            
snd_hda_codec_realtek   226308  1

snd_seq                57584  5 snd_seq_oss,snd_seq_midi_event
snd_timer              29320  2 snd_pcm,snd_seq
snd_seq_device         15372  2 snd_seq_oss,snd_seq
snd                    69412  14 snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_seq_oss,snd_seq,snd_timer,snd_seq_device
soundcore              15200  3 snd
snd_page_alloc         17032  2 snd_hda_intel,snd_pcm
Looks like I have lost snd_seq_dummy, snd_seq_midi and snd_rawmidi. I don't need midi, so I just tried to load snd_seq_dummy with modprobe. The module is not found.

I reboot another two times hoping to be able to read something in that new boot sequence text, but I don't see it anymore. It's gone.

I don't know what else to do. Any ideas?

rm /etc/asound.*
as root and then reboot. It might help.

I don't have any rm /etc/asound.* files. Maybe you have those in Slackware, but I am having this problem in Ubuntu.
