The source_name and sink_name parameters only provide an identifier for
the jack devices. Copying the alsa sink/source name won't cause the
alsa devices to be connected to the jack devices, it will only cause
naming conflicts since both the alsa and jack devices try to reserve
the same name.

After you have both the alsa source and the jack sink loaded, you need
to use module-loopback to connect them, like this:

pactl load-module module-loopback source=alsa_input.usb-ZOOM_Corporation_H1_000000000000-00.analog-stereo sink=jack_out
