when i use commond aplay to test the rt5640 , there has no sound. And the log like that:
# ./aplay -D hw:0 dynamic.wav
Playing WAVE 'dynamic.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

the output seem has no error , but has no sound.
And i did not know what happen with it. And i have some materies about the configs like that:
4005 rt5640-sound {
4006    compatible = "simple-audio-card";
4007    simple-audio-card,format = "i2s";
4008    simple-audio-card,name = "rockchip,rt5640-codec";
4009    simple-audio-card,mclk-fs = <256>;
4010    simple-audio-card,widgets =
4011    "Microphone", "Mic Jack",
4012    "Headphone", "Headphone Jack";
4013    simple-audio-card,routing =
