https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=294270 Bug ID: 294270 Summary: handbook/multimedia: Microphones not covered Product: Documentation Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: Books & Articles Assignee: doc@FreeBSD.org Reporter: bigsneaky@duck.com The Handbook does not cover microphones. Multimedia (Chapter 9) covers sound, webcams and video conferencing - the perfect place to fit microphones in? https://github.com/freebsd/freebsd-doc/blob/main/documentation/content/en/books/handbook/multimedia/_index.adoc Some ideas from this article by christos@ in the FreeBSD Journal: https://freebsdfoundation.org/our-work/journal/browser-based-edition/freebsd-15-0/vox-freebsd-how-sound-works/ e.g. recording raw PCM (Pulse Code Modulation) to a file: `cat /dev/dsp > foo` 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 part of security hardening policies so it's important to document how to do this.
