None of this surprises me. My experience with Pulseaudio tells me that
Pulseaudio is highly state dependent, and therefore acts in accordance
with historical events. Imagine having to blink your car requiring two
headlight blinks, then two key turns, then a shift to reverse and a
shift back to park, in order to start. That's what I've found
Pulseaudio to be.

I'm not so sure. We're hearing anecdotes of people running Firefox with
only ALSA. Perhaps there's some secret magic incantation that we don't
yet know about.

Also, please read https://support.mozilla.org/en-US/questions/1209469 .

Yep. play, aplay, record, arecord, speaker-test and that whole crew are
ALSA tools.
