MacBook Pro audio weirdness

Hi, all.

I’m running into an oddity with my 13" 2019 MacBook Pro.

Usually I use it in clamshell mode with an LG Ultrafine 4K display, and run the audio through that. My next most common audio output is to AirPods Pro.

Now and again, though, I need a change of scenery and shift from the home office to the dining room table, and I need to use the internal speakers.

And when I do that, occasionally there’s no sound. Just — nothing, even though the internal speakers are clearly selected for output in sound preferences.

I’m still trying to determine if there’s a pattern to when this happens.

A bit of Googling suggested killing the coreaudiod process, but the process doesn’t seem to be running for me to kill. Or at least, that’s the message iTerm gives me when I run the command, and I don’t see the process in Activity Monitor.

Logging out and back in doesn’t resolve the problem.

A full reboot does fix things, but that’s pretty annoying.

Does anyone have any ideas about what might be causing the issue?
