Remove PulseAudio device

While following instructions, I loaded a module which creates an input device “Monitor of Null Output” and an output device “Null Output” using this command:

pactl load-module module-null-sink sink_name=rmd

This is not what I wanted. How do I remove these two devices?

pactl list shows:

Sink #2
        State: IDLE
        Name: rmd
        Description: Null Output
        Driver: module-null-sink.c
        Sample Specification: s16le 2ch 48000Hz
        Channel Map: front-left,front-right
        Owner Module: 24
        Mute: no
        Volume: front-left: 65536 / 100% / 0.00 dB,   front-right: 65536 / 100% / 0.00 dB
                balance 0.00
        Base Volume: 65536 / 100% / 0.00 dB
        Monitor Source: rmd.monitor
        Latency: 1569 usec, configured 40000 usec
        Flags: DECIBEL_VOLUME LATENCY 
        Properties:
                device.description = "Null Output"
                device.class = "abstract"
                device.icon_name = "audio-card"
        Formats:
                pcm

I tried

pactl unload-module rmd
pactl unload-module sink_name=rmd
pactl unload-module "Null Output"

all of which respond with:

Failed to unload module: Module Null Output not loaded

etc.

I can run pactl unload-module module-null-sink but this removes all devices loaded with that module. How do I remove the device or unload the module which created the device specified above?

Method 1

pactl unload-module gives a hint:

You have to specify a module index or name

as does the manpage:

   unload-module ID|NAME
          Unload  the module instance identified by the specified numeric
          index or unload all modules by the specified name.

The ID is shown in this line (pactl list):

        Owner Module: 24

Just run

pactl unload-module 24

to remove the respective devices.
