Yeah. I suspect (and Mark apparently did, too) that the original
poster meant to ask about hardware monitoring, which is completely
different :-)

Explanation here:
http://ardour.org/manual/recording/monitoring

That's what the RME and ice1712 cards (among others) support...
Ardour is the only app I use that has any use for this feature.

This requires software to control the soundcard's onboard monitor
mixer. "Normal" ALSA mixers such as alsamixer will not do the job.
For the ice1712 cards, the app that does this is "envy24control".
