    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

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