update-sink-proplist does not work when setting a description containing spaces
The command pacmd update-sink-proplist some_sink device.description="A description for some_sink."
fails to change the description said sink and instead prints Failed to parse proplist.
Removing spaces (e.g. by replacing them with _) does provide the desired effect.
Notably, the command doesn't return an error, i.e. the return code is 0
