I don't know how common that is on Linux either (esp. not when using PulseAudio that forces one of 2 sampling rates on the output) but AFAIK it's quite common as a means to send "bitperfect" audio to an AV amp under MSWin. I've been doing that for the past 15 years at least, using a lowly Acer netbook as my "content server".

Anyway, if ever the OP's sound was indeed configured to go through a digital profile like HDMI there's a potential explanation for not having sound after an upgrade that I experienced myself. Probably unlikely because I can't imagine that F38 using ALSA 1.1x and F39 ALSA 1.2x but somewhere between those versions the "resource directory" was reorganised requiring a change to the system-wide and/or your personal configuration file (if you have the latter). See https://unix.stackexchange.com/questions/763254/pulseaudio-digital-profiles-ports-no-longer-appear-in-pavucontrol/763380#763380

I *suppose* it's not impossible that a personal ALSA configuration might break during a more minor ALSA upgrade, so if you do have one it might be a good idea to double-check it, or see if sound returns when you move that config file aside.
