[alsa-devel] ASoC: no dapm match for AMIC
Hi,
I am running linux-next 20141104 on a imx6q-sabresd board and noticed the following error messages:
[ 2.145602] imx-wm8962 sound: wm8962 <-> 202c000.ssi mapping ok [ 2.151654] imx-wm8962 sound: Connecting non-supply widget to supply widget is not supported (AMIC -> MICBIAS) [ 2.161710] imx-wm8962 sound: ASoC: no dapm match for AMIC --> (null) --> MICBIAS [ 2.169258] imx-wm8962 sound: ASoC: Failed to add route AMIC -> direct -> MICBIAS
What would be the correct way to fix them?
Thanks

At a guess you've got the route between the microphone and the bias for it reversed; it's hard to tell without knowing anything about the hardware.

I think you are right. If I invert the route between the mic and bias then the error disappears:
