None

There are unpopulated toslink/coax inputs on the board... do those do anything as is?

They can be used to add an input. However as almost no user needs an input, we do not populate them.

I would also like to use the SPDIF input on the Digi+. I found this topic in the forums:

http://support.hifiberry.com/hc/en-us/community/posts/201843001-Digi-SPDIF-input-

Would it still be true that to use the coax input, I would need to
- add R15 = 75Ohm
- add C9 = 100nF (can be also 220nF)
- solder an RCA connector to P4

Afterwards, connecting a SPDIF source and rebooting the Pi, I should be able to issue an arecord command?

Hi Willian,

the circuits hasn't changed. Note that we don't guarantee this will work as it is unsupported and there might be changes in the kernel that have an impact on the functionality.

Best regards
Daniel
