ALSA erkennt keine Karte, wenn sie existiert

Ich bin etwas fest damit beschäftigt, Audio in Kubuntu 18 zu reparieren (genauso wie Kubuntu 16). Das einzige Soundgerät, das ich in der Ablage habe, ist "Dummy-Ausgabe".

kosyakov@kosyakov-XPS13:~$ sudo lspci -v | grep -A 10 -i audio 00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21) (prog-if 80) Subsystem: Dell Sunrise Point-LP HD Audio Flags: bus master, fast devsel, latency 32, IRQ 134 Memory at dc428000 (64-bit, non-prefetchable) [size=16K] Memory at dc400000 (64-bit, non-prefetchable) [size=64K] Capabilities: [50] Power Management version 3 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel, snd_soc_skl 

Jedoch,

kosyakov@kosyakov-XPS13:~$ aplay -l  aplay: device_list:270: no soundcards found... 

Was ich bisher ausprobiert habe, ist das Nachladen eines Dienstes, das Nachladen von pulseaudio und aller anderen gängigen Ratschläge und Tutorials.

Und Geräte, die ich habe:

kosyakov@kosyakov-XPS13:~$ sudo find /dev/ | grep snd /dev/snd /dev/snd/seq /dev/snd/timer 

Bis jetzt bin ich fest damit beschäftigt, wie ALSA meine Karte erkennt. Ich würde mich über Ihre Ideen freuen.
