Hi,
We are using a customized TI OMAP3 with TWL4030, similar to OMAP3EVM board. We noticed occasionally (after bring up few hours) the mic channel audio is swapped. Has anyone seen similar problem? Any suggestion where the problem might be?
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?
