Hi TI：
目前项目急，等着试产。目前使用的型号是TLV320DAC3203，目前I2C是上拉到3.3V，I2C能正常访问，但是现在问题是耳机声音没有出来，下面我描述一下具体的情况，
请帮忙分析下，感谢！能否给一个TLV320DAC3203的底层驱动代码呢？
平台：RK3399， Android 9.0
内核：Linux 4.4.167
原理图：
软件配置：
DTS：
驱动使用的是tlv320aic32x4.c驱动(TI上的一些回复是说tlv320aic32x4驱动同时也能兼容tlv320dac3203，所以用这个驱动)
播放音频方法： 用下面tinyplay命令播放音频文件，用示波器量HPL和HPR引脚，没有波形出来
console:/data # tinyplay /sdcard/001.wav -D 1
Playing sample: 2 ch, 44100 hz, 16 bit
示波器量时钟：
LRCLK: 44.1KHZ
BCLK:2.82MHZ
MCLK:11.25MHZ
下面是寄存器和声卡信息：
