No. There is no physical external line/cable. My understanding is that
the PCIe bus is supposed to take care of that now. In my travels through
google and various mail lists many people with new tuner cards do not
have external cables either and are having the same problem.
To quote from a series of exchanges I have had on the Fedora users
mailing list regarding a line-in.

That is the $64,000 question. (You might be too young to
remember the $64,000 question.)
That was what started me on this whole "what do controls do?"
quest and trying to figure out various possible control
combinations. Using 'Line' or Line-in on my setup didn't seem
logical. It still doesn't.
I have external receptacles on my motherboard at the back of my
computer box -- one light green for incoming sound, and one
light red (pink) for a microphone. Double checked visually and
in my motherboard manual.
*However* my tv tuner card has no sound output receptacle, did
not come with a line to use as an external connection line and
shows no external hookups in its manual. Besides, I have looked
several times and there is no no receptacle for line-out. I
have tried experimenting with earphones. The receptacle on the
tuner card that does exist is for sound-in for a satellite dish.
On my old computer, the tv tuner did have an external line-out
sound card line-in. So I am familiar with what I am looking
for. I do not have an external line plugged into on this
computer's sound. "
Sorry, I forgot to include that info.
