I have a problem here, when I tried to overwrite pulseaudio files for specific reasons, an error comes in: ‘No polkit authentication found’. I did try to search what is a polkit and everything, downloaded the polkit auth agent for xfce and it still did not work. please help
are you trying to change Pulseaudio configuration in system files ?
It may be better to copy the configurations to home folder and customise configuration in home folder (keep system configuration as default for a backup)
cp /etc/pulse/daemon.conf ~/.config/pulse/daemon.conf cp /etc/pulse/default.pa ~/.config/pulse/default.pa
Customised Pulseaudio configuration in user home folder will override system configuration when pulseaudio is restarted
systemctl --user restart pulseaudio
man pulse-daemon.conf and
man default.pa for more information about these configuration files
