Hi，nvidia:
I’m trying to porting realtek’s 5639 codec to Nano, with nano’s I2S and I2C interface.When i use aplay to play test.wav, The following problems occur:

  1. The audio from the headphones is very quiet;
  2. The audio from the headphones is very noisy.
    Here is my debug log:
  3. aplay cmd:

aplay -D plughw:CARD=tegrasndt210ref,DEV=0 test.wav

Playing WAVE ‘test.wav’ : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
2. I2S4 output clocks:
FS: 44.1khz
MCLK: 11.29Mhz
SCLK: 1.41Mhz
3. # cat /proc/device-tree/sound/mclk-fs | xxd
