I have worked with the AT91SAM9260 on a project which is currently suspended 
(other priorities), where we had a simiar problem, with a codec on SPI.  
Every time audio was started (capture or playback) the channels could be 
swapped.  Solving that issue remains TODO when we restart.

There was a thread on alsa-devel last month 'Soc Atmel SSC stereo problem' 
with some suggestions.
