Isn't this very common with desktop hardware? For example, my laptop's
sound card has a playback volume and mute control for the "Mic" element,
which supposedly could be used for looping the mic audio to the speakers
or headphones inside the hardware.
The N9 hardware also has several possibilities for loopbacks. We used
one for the sidetone in calls (sidetone means playing back your own
voice back to you, and it's a mandatory feature in mobile phones,
AFAIK).
