I'm working on a custom board using the AT91SAM9G45 processor and a TLV320AIC26 SPI attached audio codec using I2S format audio. When doing audio playback on the board the left and right channels are occasionally flipped.

Has anybody else had this problem, or does anybody have any AT91/Atmel hardware that they could test to see if it occurs on other hardware also?
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.
