Please guide me as soon as possible. It's very urgent for me.

Hello,

Apologies for the delay in responding.

I believe this is achievable, though we don't have an exact sample that implements it. PDM input is used when CONFIG_STREAM_BIDIRECTIONAL is enabled, and audio is output to the headphone jack when CONFIG_AUDIO_DEV=1 is set. You can refer to the audio_datapath.c file for more details.

Kind regards,
Abhijith
