LyraT-Mini v1.2 recording issue (silent sound)

Dear ESP-ADF community, I encountered a strange recording issue with LyraT-Mini v1.2.

As for the demo project pipeline_recording_to_sdcard (https://github.com/espressif/esp-adf/tr ... _to_sdcard), LyraT-Mini v1.2 is able to run but the recorded sound is silent. Already applied idf.py menuconfig and select "Audio HAL > Audio board (ESP32-Lyrat-Mini V1.1)".

If the same project runs on "ESP32-LyraT V4.3" (menuconfig to select the corresponding HAL), it can record normally. I opened a Github issuehttps://github.com/espressif/esp-adf/issues/744 as well.

It seems to be the wrong env/settings that cause the issue.
May I have some hints about this? Thanks
