SB X-Fi Titanium HD JP2 pinout

Sound Blaster X-Fi Titanium HD
The expansion port is labeled JP2.

The old audigy/sb Live AUD_EXT Pinout (above right) does not match this sound card!!!! This image is provided for curiosity only.


A standard 40 wire IDE cable is able to be plugged into the JP2 port, which I used to make testing the individual pins easy. Pin 1 (the Pink wire) corresponds to the marked arrow.

Voltages of JP2 in Millivolts:

Hi, I saw your old post regarding the Creative SB Titanium HD looking for the pinout for SPDIF to use with coax. I recently am looking for the same information and was wondering if you had figured out anything newer since 2015 when you posted.

I examined the circuit traces and did some meter tests, and got similar results to what you had. I think this may be a mostly correct pinout.

SB1270 Pinout
1 nc 2 GND
3 nc 4 nc
5 GND 6 nc
7 +3.3v 8 GND
9 +2.5v 10 SPDIF In ??
11 GND 12 SPDIF Out ??
