Raymond tends to be side-tracked from time to time and ask questions
which are related to your original issue. Also apologies for not having
read the entire thread through.

PulseAudio closes the audio stream five seconds after no applications
are active, so that's probably when the issue goes back to normal too.

The resampler changed from "null" to "copy" means that we have a
resampler engine active for the stream, but all it does is to convert
from s16le (as being input by Chrome) to s32le.

You're probably hitting a driver issue, but I wonder how we can prove
it. Also the fact that it seems to hit one application only is a bit
strange, maybe it's related to the requested latency by that specific
application or something.
