您好：
调试 TLV320AIC3101时碰到如下问题：
机器每次重启后，使用以下tinymix命令打开HPLOUT / HPROUT通路（LEFT_LOP/M 和 RIGHT_LOP/M 情况也一样）,然后用tinyplay播放48 KHZ 1k-0db的音频文件,有时会有声音,有时没有声音,比较两种情况下codec寄存器是完全相同的(参见附录reg-tinymix.txt)用示波器测量两种情况下 各个CLK和 电源 也相同（播放时DIN 也有信号）频率及电压如下:
MCLK:12MHz
BCLK:3.07MHZ
LRCLK:48KHz
DVDD: 1.8V
IOVDD: 3.2V
DRVDD: 3.3V
AVDD_DAC: 3.3V
电源上电延时情况：
I0VDD->(500ms)->AVDD/DRVDD->(2ms)->DVDD
