After some examining, it appears the issue only affects USB audio devices, and dependent on the quality of the USB port they are plugged into.
Minecraft version 1.20.1 and older - no issue. Releases 1.20.2 onward (up to 1.21.4), sound may work occasionally, but more often not.
The only audio devices affected appear to be those over USB. The on-motherboard Realtek sound works. Nvidia audio (speakers in the monitor) works. Logitech Pro-X wireless USB headset did not work.
However, plugging the headset receiver into a different USB 3.0 port appears to have fixed the issue. Of note, however, is that the headset worked just fine for all other applications, even when receiver was plugged into a slower port.
