DMIC input volume very low

[anushan]

Hello Everyone,

I am trying to record voice through the dmic present on my board, the audio codec used is wm8962, the codec provides 1.8v to the dmic and dmic clock runs at 2.8MHz. But, when I record anything through the dmic i am not able to hear anything in the playback.

Kindly help to find a solution.

Regards,

Anusha
