This is because the configuration file uses this format for sections:

[<type> <name>]

Here the section type is "Jack" and the name is "Speaker".

All jack controls in alsa have "Jack" at the end of their name (that's
how PulseAudio recognizes that they are jack controls), so in this case
the alsa control name is "Speaker Jack". We could write [Jack Speaker
Jack] in the configuration file, but that would be ugly.
