On Ubuntu 16.04 (LTS), x64, I am facing the following problem: .xsession-errors, in home folder is growing very fast, reaching sizes of tens of GB.

I just forcibly truncated the file (echo "" > .xsession-errors ), as a temporary fix, then copied the file that started growing again, to a different location, to inspect what is going on.

Looks like the file is filled with the following lines, repeated over and over again.

org.kde.plasma.pulseaudio: Attempting connection to PulseAudio sound daemon org.kde.plasma.pulseaudio: state callback org.kde.plasma.pulseaudio: state callback

Any hints on how I could fix this? I am not using / don't need sound on the machine.

Looks like your KDE is configured to use Pulse Audio as an engine for Phonon Backend, and for some reason the Pulse Audio daemon itself is not installed/not responding.

I suggest you make sure the phonon-backend-gstreamer is installed:

sudo apt-get install phonon-backend-gstreamer

and then go to KDE audio preferences and check that "Gstreamer" is configured as a backend.

Completely uninstall pulseaudio and make gstreamer use alsa instead:

sudo apt-get purge pulseaudio gstreamer0.10-pulseaudio
sudo apt-get autoremove

sudo apt-get install alsa-base alsa-tools alsa-tools-gui alsa-utils alsa-oss linux-sound-base alsamixergui

sudo apt-get install esound esound-clients esound-common libesd-alsa0 gnome-alsamixer

Then restart your computer.

After that, run

gstreamer-properties

to setup Gstreamer defaults (which now will use alsa).

Then check if the errors related to Pulse Audio go away.

One option, edit the file /etc/X11/Xsession, for example:

sudo nano /etc/X11/Xsession

Then modifty the ERRFILE variable so errors are sent to /dev/null.

## ERRFILE=$HOME/.xsession-errors
ERRFILE=/dev/null

    Hello and welcome to Super User! While this may fix the .xsession-errors file growing out of control, I think the real problem the OP is asking about is the continuous output of PulseAudio errors.

    Re: Welcome from Mr Shunz! comments .... While this may fix the .xsession-errors file growing out of control, I think the real problem the OP is asking about is the continuous output of PulseAudio errors. That is why I said "One option" and didn't say preferred option etc. I did find other "solutions" eventually, perhaps you could have posted one of those instead of an irrelevant comment on the fact that there might be better solutions? In the file I mention you can also alter the max file size for instance ....
