Analog and digital microphones on the G520

Hi MTK team,

Platform: Genio 520 (MT8391), Android 15

Current status:

2 analog microphones (AMIC) are working correctly via PMIC

Audio recording path is verified

Questions:

What is the correct way to fully disable the AMIC in the audio stack?

What is the correct configuration to enable 4-channel DMIC on MT8391 (audio_device.xml, and DTS, ProjectConfig.mk,…)?

Thanks.
