The AMIC function is loaded by default and no changes to the DTS configuration are required.As with DMIC, use the audio_all_test_case program to test:

# ./audio_all_test_case -t 20 -I -o /tmp -d 0 -m 0 -c 2 -s 48000

Chn0_Amic_48K_16bit_MONO.wav and Chn1_Amic_48K_16bit_MONO.wav will be generated in the /tmp/ directory.If there is a LineOut interface, you can directly play the recording file and judge whether the recording is successful.
