Trying to identify sound card connectors

I just bought an old Sound Blaster Live! 5.1 PCI CT4780. There are a
number of connectors on the board, and I would like to identify them and
know why some of them came with jumpers on various pins.
J1 - 1 row of 10 pins
J12 - 1 row of 4 pins (TAD)
J9 - 1 row of 4 pins (CD_IN)
J4 - 1 row of 3 pins
J11 - 1 row of 4 pins (AUX_IN)
JP1 - 1 row of 2 pins
J3 - 1 row of 2 pins (CD_SPDIF)
JP3 - 1 row of 3 pins
J13-2 - 2 rows of 5 pins = 10 pins
J13-1 - 2 rows of 14 pins = 28 pins (AUD_EXT)

I'm guessing that TAD stands for "telephone answering device", and the
two "CD_" connectors are obviously for connecting an optical drive. But
what are the rest of the connectors for? Are they all inputs? What can be
connected to them?

Also, JP4 and JP3 each have jumpers connecting their pins 1 and 2. J13-1
has two jumpers on it: one connecting pins 21 and 23, and another
connecting pins 24 and 26.

What purpose do these jumpers server? If I can't figure it out, should I
remove them?

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
peripherals.

Hope this helps

They're to connect up the 5 1/4" Liveddrive bay thingy Creative do which
has a load of controls and inputs/outputs on.

Yes, the previously linked manual indicates that the J13-1 and J13-2 are
connected to a single plug that leads to an optional drive-bay/front-
panel accessory, in which case I imagine that thier jumpers would have to
be removed.

But there are still the 3-pin JP3 and JP4 which each have jumpers
connecting pins 1 and 2.

It would be nice to know what those are for.
