Mono audio, no pulseaudio file

Trying to get my audio interface to output mono audio, finding on here to add the following to the file:
load-module module-remap-sink sink_name=mono master=[youraudiosink] channels=2 channel_map=mono,mono
…but interestingly, I do not have a file in either the /etc/pulse/ or ~/.config/pulse/ on my new Kubuntu installation. I created a file then, in ~/.config/pulse/, putting just that line in there and no luck. Checked the audio settings and no remapped sink is created.
Maybe related when trying to get my audio sinks using “pacmd list-sinks”, I get output: No PulseAudio daemon running, or not running as session daemon.
edit: Kubuntu 22.10
