It depends how pulse is set up. If pulse is also connected to the internal

there is some confusion here. the pulse jacksink/source modules connect
pulse to JACK, not vice-versa. JACK will be using whatever hardware it was
told to use. the only situation in which JACK routes audio via Pulse is if
the user tells JACK to use an ALSA PCM device that is actually a pulse
pseudo-device (eg. "default" on a system set up with Pulse as the default).
Pulse may or may not work in situations where JACK is running, and if there
is only one audio interface and its used by Pulse, then JACK may not be
able to start either. But Pulse cannot intervene at the ALSA level seen by
JACK unless the user tells JACK to use the "wrong" device name.
