Oh, I assumed you had added module-device-manager to default.pa, since it's not
there by default and you had it loaded, but I forgot that it's loaded by
/usr/bin/start-pulseaudio-x11 when you start a KDE session. The reason why you
see the crashes only after booting is that after pulseaudio has crashed and
restarted, module-device-manager isn't loaded any more, and
module-device-manager is somehow involved in this (I don't know yet if the root
cause is in that module, though).

I'm able to reproduce a crash. It's a different assertion, however: E:
[alsa-sink-CX20561 Analog] sink.h: Assertion
'pa_object_refcnt(pa_object_cast(o)) > 0' failed at ./pulsecore/sink.h:308,
function pa_sink_assert_ref(). Aborting.

I don't use KDE and I use pacat/parec to simulate Zoiper. These are the steps
that I use to reproduce the crash (I don't know if all of them are necessary):

1) pactl unload-module module-switch-on-port-available

2) pactl load-module module-device-manager do_routing=true

3) pactl set-card-profile alsa_card.pci-0000_00_1b.0
output:analog-surround-40+input:analog-stereo

4) PULSE_PROP="filter.want=echo-cancel media.role=phone" pacat /dev/zero (leave
running)

5) PULSE_PROP="filter.want=echo-cancel media.role=phone" parec > /dev/null
(leave running)

6) pactl set-card-profile alsa_card.pci-0000_00_1b.0
output:analog-stereo+input:analog-stereo

I'll continue the investigation.
