Yes, 20 seconds is the time after which it stops to play. I have that
time in daemon.conf. I listed modules loaded in pacmd and
module-x11-publish is really the only one making the difference. If it
should not have any impact then there is still a possibility of
incorrect linking/building (I use only the archlinux published binaries
now - so hopefully they did it right) or some kind of dangling pointer
problem or whatever ...
I tried not to load x11-publish and load suspend-on-idle. Suprisingly it
does not exit when playing line-in loopback source (if pulseaudio is not
interacted with otherwise).
It almost looks like the two modules have switched names (but then they
would be switched in pacmd list-modules too).

Regardless of the combination of loading of suspend-on-idle and
x11-publish. When I enter pacmd do list-modules and exit it, then
pulseaudio server exits immediately too.
Hmm and pavucontrol and pavumemter has almost the same effect (it just
does not exit immeditally but after about 20 secs after I exit
pavucontrol or pavumeter).
It is a mess. Or maybe it is not. May be it exits 20 secs after startup
or 20 secs after any apllication interacts with pulseaudio server ...
and pacmd is special it allows the exit to happen but does not reset the
counter back to 20 seconds.
Ok, if you have any idea what I should try, let me know. I may not do it
immediately (especially if it is not something quick). But I'll do it
eventually. I'm a developer, though I do not know pulseaudio ... not
even at a level of a skilled user. Uff, I would prefer not to be a
pulseaudio developer too :)
Hopefully some pulseaudio developer can repeat this (if it is not
archlinux build/link problem).
