I'm using ALSA sound library. When i use CAPTURE mode, sometimes it swaps left and right channel. I have found this discussions on Internet, where is described similar problem: http://pl.it-usenet.org/thread/17996/3593/ http://sinustrom.info/2013/03/21/atmel-soc-ssc-channel-swapping/ I have figured out, that the problem could be in driver or in ALSA library. Have you any solution ? Did you encountered similar problem ?
