Off-Topic • Capture controls in Alsamixer locked to zero

I have an IBM ThinkPad 600X on which I have installed Debian based antiX 23.1. Initially, the system could not find any driver for the audio device.
After following the instructions for Debian 8 "Jessie" in the Debian Wiki for snd-cs46xx, I now have an snd-cs46xx driver.
