Bug Description

After using the following commands to create a mixer to add a soundboard to a mic input using pulseaudio, I notice that the "device description" is displayed correctly in each tab, but in the "Recording" tab it just shows "Null Output" for each device.

pactl load-module module-null-sink sink_name=MUSIC
pacmd 'update-sink-proplist MUSIC device.description="Dummy Input"'
pactl load-module module-null-sink sink_name=MIXER
pacmd 'update-sink-proplist MIXER device.description="Dummy Mixer"'
pactl load-module module-loopback sink="alsa_output.pci-0000_00_1f.3.analog-stereo"
pactl load-module module-loopback sink="MIXER"
pactl load-module module-loopback sink="MIXER"

Screenshot attached

As you can imagine, it makes it hard to work out what's going on when devices all have the same name!
