Hello Matthias :-) Yes the same here, I have to manually restart
PulseAudio on hotplug. Maybe a system wide service with DEVD hooks would
do the trick.. but I prefer to run it as user :-)

Not really with FF but you may want to take a look (man snd) and sysctl:
hw.snd.default_unit <- you can set the default unit
Default sound card for systems with multiple sound cards. When
using devfs(5), the default device for /dev/dsp. Equivalent to a
symlink from /dev/dsp to /dev/dsp${hw.snd.default_unit}.
hw.snd.default_auto <- this is useful for hotplug (=2)
Automatically assign the default sound unit. The following
values are supported (default is 1):
0 Do not assign the default sound unit automatically.
1 Use the best available sound device based on playing and
recording capabilities of the device.
2 Use the most recently attached device.
I usually set hw.snd.default_unit=3 in /etc/sysctl.conf to set default
to my external USB SoundBlaster that is connected to a hifi audio system
and loudspeakers.
I noticed that setting hw.snd.default_auto=2 switches sound to hotplug
USB headphones that I use for online video conferecing :-)
But still I need to manually restart local user PulseAudio process after
hardware setup changes so FF gets the updated info on available audio
devices. I usually just run `pulseaudio -k` to make it stop and the
Enligthenment starts is again for me.
Quick peak at PulseAudio homepage shows that we work on an outdated
version. FreeBSD uses 13.0 from 2019-09-13 while the latest release is
14.2 from 2021-01-16. There is a mention on hot plug in the manual page.
Maybe we should update the port first and see if the issue is solved
already in the upstream? :-)

This echotest is awsome because is also shows video :-) For audio
testing I find visual audio waveform helpful:
