No sound with an Intel processor of the 11th generation or more

Problem

Intel expects users of their most recent processors to rely on a signed binary firmware to get sound. The source code is distributed under a free software license. However, without the Intel key to sign the produced binary, one cannot actually use a modified version. It is tivoization.

Solution

The kernel driver snd_hda_intel actually provides sound (on some systems at least) after blacklisting the more recent modules. Execute in a terminal the following command line:

$ printf 'options snd-intel-dspcfg dsp_driver=1\n' | sudo tee -a /etc/modprobe.d/alsa-base.conf

Reboot and, hopefully, enjoy sounds!
