(Note: this is not an alphabet post. You may have noticed I'm a little stuck on I. I hope to get un-stuck soon; but first, here are a pair of articles on configuring audio on Linux.)
I'm a very late adopter for PulseAudio. In the past, on my minimal Debian machines, nearly any sound problem could be made better by apt-get remove pulseaudio. But pulse seems like it's working better since those days, and a lot of applications (like Firefox) require it, so it's time to learn how to use it. Especially in these days of COVID-19 and video conferencing, when I'll need to be using the microphone and speakers a lot more. (I'd never actually had a reason to use the microphone on my last laptop.)
Beginner tutorials always start with something like "Go into System Preferences and click on Audio", leaving out anyone who doesn't use the standard desktop. The standard GUI PulseAudio controller is pavucontrol. It has four tabs.
