Multimedia (Chapter 9) covers soun= d, webcams and video conferencing - the perfect place to fit microphones in? https://github.com/freebsd/freebsd-doc/blob/main/documentation/content/en/b= ooks/handbook/multimedia/_index.adoc Some ideas from this article by christos@ in the FreeBSD Journal: https://freebsdfoundation.org/our-work/journal/browser-based-edition/freebs= d-15-0/vox-freebsd-how-sound-works/ e.g. recording raw PCM (Pulse Code Modulation) to a file: `cat /dev/dsp > f= oo` then playing it back with `cat foo > /dev/dsp`, or crude input monitoring to check the microphone works, `cat /dev/dsp > /dev/dsp`. Selecting and muting recording sources with mixer(8). More generally, some guidance on setting up and disabling microphones would= be valuable. Note that some workplaces require microphones to be disabled as p= art of security hardening policies so it's important to document how to do this.
