I have not experienced with channel swapping during capture..
It would help, if I know:
what is your kernel version
Source of the recording (digimic, HS, main mic, etc)

To clarify:
you experience sudden channel switch during active recording, when
the recording was running for few hours?
Or is it that you start/stop the recording, and sometimes the channels
are swapped?
