Ok, this is weird. Since you were asking for more info I tried to
collect a backtrace / logs. But what is happening is that after
the snd_hdmi_lpe_audio module loads, pulse does its thing and
then exits with a message of "killed" in gdb / on the terminal
from which I started it. I don't get a chance to get a backtrace
in gdb ... So this does feel like a kernel bug to me, normally
this sort of "killed" behavior is seen on some kernel oopses...
But dmesg is free of any oopses ?
Anyways here is a log of pulseaudio -v first without the
hdmi module and then the module gets probed. Where the log
abruptly ends is where I got the "Killed" message on the
terminal.
