Debug output

I have a Lamina 2-in-1 tablet running Debian testing (buster). After an update
to Linux 4.12 sound stopped working in the GNOME session, however sound is
still working in GDM (I can change the volume using the volume slider in GDM's
top menu, and the "plopping" sound is playing then). However inside the actual
GNOME session as the regular user, PulseAudio is not running. I can see a
pulseaudio process running as the GDM user with the command line:
/usr/sbin/pulseaudio --daemonize=no

I tried manually running it from the user session (using /usr/bin/pulseaudio
--daemonize=no --log-level=debug and it seems it crashes.
I have attached the debug printout from the manual run session and the output
of lspci and lsmod, which I think might give hints.
