That's the FireWire DV Sound Input component you are seeing. It only
does interesting things if you hook a FireWire DV camera up to the
computer and are actively capturing data from it. You use the
siDeviceConnected info selector to find out if there is a camera
attached to the component.
It doesn't appear in the HAL because there isn't an IOAudio driver for
it.

Could anybody here enlighten me about the "DV Audio" sound input? It
appears as a
possible sound input device from the point of view of the Carbon
SoundManager, but recording
from it doesn't seem to work. From the point of view of CoreAudio, it
seems to be totally
absent, i.e. no device with this name exists and the Built-in audio
device doesn't have any
input source with this name... This is on a PowerBook G4/667, MacOS
10.2.1, but the same
behaviour seems to appear on a variety of configurations. Thanks for
any comment on that,
