"h/w monitoring" as presented by Ardour and JACK as an option is
controlled by JACK. if you have not enabled it or it is not available
for your audio h/w, then it will do nothing. It is similar to the ASIO
DirectMonitoring support, and allows JACK clients (e.g. Ardour) to ask
JACK to enable h/w-based monitoring for a specific channel. It is very
limited (you can only monitor the input of channel N on the output of
channel N). Moreover, at this time only 3 types of audio interface (the
hammerfall series, the hdsp series and any cards based on the
ice1712/ice1724 chipsets) have support within JACK to enable this.

"h/w monitoring" used in reference to the capabilities of a particular
audio interface has nothing to do with JACK or Ardour. It is something
that you have to control with another program, typically one
specifically aimed at that type of audio interface (e.g. envy24control,
or hdspmixer).

in ardour 2.0, we refer to this 2nd meaning of "h/w monitoring" as
"external monitoring".
