Hi,
I finally managed to connect the MIC_N and MIC_P inputs to the RV1103. Which drivers for the internal codec should I install?

Hello, in the default image of RV1103, the audio-related device tree and kernel are already configured. If the external circuitry is correct, you can use
Code: Select all
rk_mpi_ao_test -i <custom pcm>.pcm --sound_card_name=hw:0,0 --device_ch=2 --device_rate=16000 --input_rate=16000 --input_ch=2
to test if the audio playback function is working properly

Could you please share what kind of microphone did you connect and how? How did you manage to test it with included software?
thanks in advance.
