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?
Is this with recent kernels? There were this channel swapping problem before but it got fixed by Eero Nurkkala for the 2.6.32 kernel by following commits:
commit 9abea08e43c6cfc18399e42cbc6028d111532f61 "OMAP: McBSP: Provide functions for ASoC frame syncronization" and commit ca6e2ce08679c094878d7f39a0349a7db1d13675 "ASoC: Always syncronize audio transfers on frames"
