I think Ubuntu needs to provide the jack plugin as part of libasound2-plugins as ALSA intended.
The jack related readme and example conf as in the package, but no driver
dpkg -L libasound2-plugins | grep -i jack /usr/share/doc/libasound2-plugins/README-jack /usr/share/doc/libasound2-plugins/examples/asound.conf_jack
