How does the Google Meet or Jitsi software interact with jackd? Does
chromium support jackd natively now, or are you using pulseaudio jack
module?

My guess (only a guess, but I would be open to discussion of ways to test
the hypothesis) is that changing the buffer size either reduced dropouts
in the jackd to browser interface (which I assume is probably pulseaudio
jack module, which is known to have some problems at low jack buffer
sizes), or the larger buffer size rippled through to the browser interface
and allowed the meeting software to process fewer buffers, reducing
dropouts in the meeting software somewhere, either browser implementation,
or server (if a central server was used rather than peer-to-peer), or at
the other end of the connection.
