Are you sure OUT is not PB8? PB13 seems odd..

Assuming it's PB8 then

PB8 = I2S_DO / AC97_DO
PB12 = I2S_DI / AC97_DI

which makes perfect sense. AC97 is audio, DO/DI == digital output/input.

but

PB13 = SPI2_CSI

which is an entirely different function group not at all related to
audio.


Another comment: Reading the pin descriptions. Pin group E & G, TS is
MPEG Transport Stream, I.e. where you plug in DVB receivers and the like
without having to pass the full transport stream via the ARM CPU. The
A10 have two Transport Stream interfaces (TS0 and TS1). 

The EVB manual explains pretty well what functions A10 have. You can
find a roughly translated version at
http://www.henriknordstrom.net/code/A10/doc/ based on Google Translate
and some manual edit to make sense.
