OK, I'm not 100% certain on some of these, but I'll do my best. This
information is based on my Creative Sound Blaster Live CT4830, and on
some general knowledge I have as a nerd, quite a bit of which was gained
recently when researching pinouts for internal computer plugs, including
those on sound cards.
J1 - 1 row of 10 pins
This can be used to connect the front audio jacks on your tower case to
the sound card, you may well need an adapter.
J12 - 1 row of 4 pins (TAD)
You have the correct answer (telephone answering device). I'm unsure if
this is bi-directional, and I don't know all that much about it,
although a Google search should yield some answers.
J9 - 1 row of 4 pins (CD_IN)
Connect a CD drive to transfer ANALOG audio.
J4 and JP3 - each 1 row of 3 pins
Is there a jumper on either of these? Usually, a row of three pins with
a 2-pin jumper changes a setting, such as C/LFE assignment: In one
position, C will be on the tip and LFE will be on the band (and they
will ground through the sleeve), in the other position, LFE will be on
the tip and C will be on the band (and they will ground through the
sleeve). C/LFE in case you don't know is the center / sub-woofer (low
frequency emitter). if they both have jumpers, then I don't know what
the other is for, it might be the case that neither is C/LFE assignment.
If neither has a jumper, then again, I don't know.
J11 - 1 row of 4 pins (AUX_IN)
Basically another CD_IN by a different name.
JP1 - 1 row of 2 pins
Possibly for connecting the speaker or buzzer inside the tower, although
mine calls this J7 PC_SPK.
J3 - 1 row of 2 pins (CD_SPDIF)
This transfers DIGITAL audio from a CD drive using the Sony/Phillips
J13-1 - 2 rows of 14 pins = 28 pins (AUD_EXT) and J13-2 - 2 rows of 5
pins = 10 pins
This is actually 1 jumper, the reason for the separation is to allow for
two key pins to correctly orientate the plug. This jumper is used to
connect devices such as the front 5.25" bay accessory (Live Drive). I
believe there is also a version of that which fits into the PCI slot in
the case (not the one in the motherboard).
Hopefully that helps.

Disclaimer... I might be wrong as I'm going from memory.
Back in the day when the SoundBlaster Live! card was the daddy it came in
three different versions. Each version shared a common main sound card. The
basic version was just the sound card. The next version up had a faux-pcie
card that provided some pro-level outputs (and possibly a game controller
port) on its backplate. The top of the range model had a panel that fitted
into a disc drive bay to provide front panel controls.
I believe that the extra pins etc that you mention are used to connect these
Hope this helps
