Ubuntu, sound disappeared

• Ubuntu 21.04, 64 bit.
• Just updated to kernel 5.11.0-25-generic and sound disappeared.

modprobe snd-hda-intel

Displays absolutely nothing. No error message, no missing. Nothing. Is that expected?

Any ideas?

• I tried to add options snd-hda-intel dmic_detect=0 to alsa-base.conf. Still no luck. Purged and reinstalled pulsaudio packages, alsa packages. Still no sound.
• Also tried instead to add options snd-hda-intel model=generic still no sound.
• Tried to use previous kernel, still no sound.

It was fixed with this: https://askubuntu.com/a/1249071/877575

Wondering why reinstalling all packages did not fix this.
