Does anybody have a small-ish code snippet that reproduces this issue, or can point me in the right direction to write one?

After having tried many solutions, this has worked!
For future reference, the issue I was experiencing was with the "Spoken Content" accessibility feature starting to glitch and pause the audio.
I could see multiple instances of the coreaudiod process outputting the following in Console.app:
coreaudiod Audio IO Overload thread: 5debaa inputs: '<private>' outputs: '<private>' cause: 'Unknown' prewarming: no recovering: no
