The module-x11-publish error is probably caused by
/etc/xdg/autostart/pulseaudio.desktop, which is loaded on login,
causing /usr/bin/start-pulseaudio-x11 to be run. You could try removing
the pulseaudio.desktop file (take a backup if you want). You shouldn't
lose any essential functionality by doing that (and since PulseAudio
was unable to connect to X11, whatever PulseAudio wanted to do didn't
succeed anyway).

If you see "Device or resource busy", something else is using the ALSA
device. You can check with "lsof /dev/snd/*" what programs are using
the ALSA devices.
