[NanoPi-NEO-Core2, Armbian Stretch, H3 Audio Codec MIC Input Not working]

This issue is common to the NanoPi NEO Duo (H2 + Core) / NanoPi NEO Core (H3 Core) / NanoPi NEO Core2 (H5 Core).

[NanoPi-NEO-Core2, Armbian Stretch, H3 Audio Codec MIC Input Not working]

The same problem is still continuing.

The first is the abnormal operation status log, and the second is the normal operation status log.

The first one works with the Armbian Debian_stretch_next_4.14.78 firmware and the second one with the FrandelyARM firmware.

Is there any way to improve this?

The NanoPiDuo board is the same symptom.
The following logs are left.

[NanoPi-NEO-Core2, Armbian Stretch, H3 Audio Codec MIC Input Not working]

I tested with Armbian Stretch image on NanoPi-NEO-Core2.

PJSIP VoIP Client. MIC input does not work.
Additional USB sound cards work well.

In FriendelyARM original firmware, MIC input works well.
I hope that this issue will be resolved.

Please help me.
