    Hello Hayashi, I was able to confirm my above test from our TI expert and you can pick either the mic or line input configuration for your analog type signals and expect normal operation within the device. Regards, Ore.

    Hi Richard, Okay. I'd be curious to know how it works across multiple boards, as it may be a layout quirk. Either way if you're happy with the solution, I don't see a problem with it going forward. Best regards, Jeff McPherson
