Apparently autospawning is enabled for gdm. That's weird. My impression has
been that Arch disables autospawning (as it should when it's using systemd to
manage pulseaudio), and autospawning seems to be disabled for your own user. Is
there some gdm specific configuration in
/var/lib/gdm/.config/pulse/client.conf? Make sure that /etc/pulse/client.conf
has "autospawn = no". Note that /etc/pulse/client.conf has no effect on gdm if
/var/lib/gdm/.config/pulse/client.conf exists.

The log stops rather abruptly in the middle of the probing process after
getting "Input/output error" from snd_pcm_hw_params(). It seems that
snd_pcm_close() is hanging, because otherwise there should be more logs.
To me this seems quite clearly a kernel bug, and I don't think I have much more
to contribute here. You should report the problem to the alsa developers, here
are some instructions: <a href="http://alsa-project.org/main/index.php/Bug_Tracking">http://alsa-project.org/main/index.php/Bug_Tracking</a></pre>
