Pulseaudio configuration may have changed following update but might still retain old configuration settings
try clearing pulseaudio configuration in home folder
rename user configuration folder to ‘pulse.old’ and restart system
mv ~/.config/pulse ~/.config/pulse.old && reboot
when Pulseaudio restarts it will create new configuration files

EDIT: error in folder name ‘~/config’ changed to ~/.config/’
