:) I'm afraid my English is not quite up to the task, but it's fun to try.

It seem so, that no cunning foe is stealing the resource, for the
great Jack D.'s voice to be heard.

So the humble scholar found another word of hope, buried deep within
the arcane tomes:
for the .asoundrc spell, for the rite to be complete
that will allow the foreigners to be heard by Jack D.,
the caster needs an artifact, a mystic scroll from the Great Library,
and that scroll is named /usr/lib/alsa-lib/libasound_module_pcm_jack.so
and can be summoned with the magic words:
# sudo USE="jack" emerge -av media-plugins/alsa-plugins
