I'm not an audio specialist, so the symbols used to
identify the ports look like hieroglyphs to me, but 
The documentation says that the two ports on the
back are for headphones and external stereo loudspeakers.

And the sound is definitely i2s given the OF entry:

/proc/device-tree/pci@f2000000/mac-io@17/i2s@10000/i2s-a@10000/sound/device-id
