  • Check logfiles, look for pulseaudio lines. It seems to be crashed. – Ipor Sircer May 23 '18 at 11:24

It might be because either your pulseaudio driver is broken and/or has permissions set to root.

I had solved this problem with the following commands :

# clean and reinstall pulseaudio
sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio
sudo apt-get -f install && sudo apt-get -y autoremove && sudo apt-get autoclean && sudo apt-get clean && sudo sync && echo 3 | sudo tee /proc/sys/vm/drop_caches
# fixes user folder permissions
sudo chown -R $USER:$USER $HOME/
# then reboot
sudo shutdown -r -t 0

Pulseaudio should be started at startup but you can manually start it with :

pulseaudio --start

If the problem persists, feel free to paste your system log here

tail -100f /var/log/syslog
0

For my pulseaudio "connection refused" issue the following helped:

mv -v ~/.config/pulseaudio{,~}

This way the pulseaudio userspace configuration is reset (without destroying the old). No reinstall or reboot was needed.
