This is the first time I have heard of channel swapping related to capture on OMAP platforms. In playback case we can still have corner cases, when channels would swap/shift, but in capture? The only thing that I can think of is FIFO overflow, when odd number of word got discarded, so from application point the channels would swap. -- = P=E9ter
