Are you sure in the last EOMA68 A20 Boards have this conector?¿?

In the news Photos of working examples in april and may dont see this conector

In the case of A20 plate actually incorporates an auxiliary bus 44pins.

It would be possible to extend or modify the bus to enter the i2s??

If I'm right in the project OLINUXINO implemented several lines of cpu
to the same pin expansion connectors with a choice of system function

For us this would be the second option since we have found that using
converters usb light generated synchronization delays in the video /
audio. that must be corrected through the player (XBMC - MPlayer).

By contrast, in the tests we've done with CPU integrated SPDIF not
have these delays. (Important in case of decoding DTS or DOLBY)
