Hello GL1zdA!
I was searching for this years ago. All I could find back then was the location of SPDIF out pins on SB0880 (attached), hope this helps somehow.

I'm not sure about the Titanium HD, but other X-Fi's share the same connector as the Audigy 2. Just like the SB Live and Audigy 1 share the same connector and the Live Drives are interchangeable.

Here's the mapping for the X-Fi and Audigy 2.

Edit: Note the comment at the bottom, if it's the same connect many of those things can't be enabled without a real Live Drive. There might be a work around but I've never seen one documented for the X-Fi cards.

You can't do anything useful with Titanium HD internal feature connector. Sure, probably can plug SPDIF, but there's regular Titanium for that.

This is the problem. What you posted is the original X-Fi pinout (the PCI version), like the SB0480 one:

These were using the "classic" I/O Drive:

The X-Fi Titanium cards (the PCIe ones) used a totaly different I/O Drive:

Finally, the X-Fi Titanium HD has a connector, but it was never sold with anything, that could be attached to it.

What I was hoping for was a MIDI out for the Titanium 🙁

Wow, I never saw that thing before. It's pretty disappointing in its IO compared to earlier models.

If you're looking for MIDI out, your best bet is a USB MIDI Cable. They add MIDI in and out ports that are selectable in software and will work the exact same way as the MIDI ports on an older Live Drive.

The MIDI on the Live Drives actually has a problem with those mini connectors it uses. They are difficult to source, pretty much everything you'll find are AT to PS/2 keyboard adapters which are a different pin out.
