MCLK:12.5M，BCLK:3.13M，FS：48K.
使用I2S音频数据作为DAC输入，LOL和LOR一直输出0.9v。配置如下：
void AIC320_init(void)
{
AIC320_Write_Byte(0x00,0x00);//Initialize to Page 0
AIC320_Write_Byte(0x01,0x01);//S/W Reset to initialize all registers
HAL_Delay(10);
// CLOCK SETTINGS
AIC320_Write_Byte(0x00,0x00);//Initialize to Page 0
AIC320_Write_Byte(0x0b,0x81);// Power up the NDAC divider with value 1
AIC320_Write_Byte(0x0c,0x82);// Power up the MDAC divider with value 2
//AIC320_Write_Byte(0x0d,0x00);// Program the OSR of DAC to 128
//AIC320_Write_Byte(0x0e,0x80);// Program OSR for DAC to 128 (LSB)
AIC320_Write_Byte(0x3c,0x08);// Set the DAC Mode to PRB_P8
//;# ANALOG POWWER SUPPLY
AIC320_Write_Byte(0x00,0x01);// Select Page 1
AIC320_Write_Byte(0x01,0x08);// powering up internal AVdd LDO
AIC320_Write_Byte(0x02,0x01);// Enable Master Analog Power Control
AIC320_Write_Byte(0x7b,0x01);//Set the REF charging time to 40ms
AIC320_Write_Byte(0x00,0x01);// Select Page 1
AIC320_Write_Byte(0x14,0x25);//
AIC320_Write_Byte(0x0a,0x00);//Input Common mode set to 0.9V
//;# AUDIO ROUTING
AIC320_Write_Byte(0x0c,0x08);
AIC320_Write_Byte(0x0d,0x08);
AIC320_Write_Byte(0x0e,0x08);// Route Left DAC to LOL
AIC320_Write_Byte(0x0f,0x08);// Route Right DAC to LOR
AIC320_Write_Byte(0x03,0x00);//Set the DAC PTM mode to PTM_P3/4
AIC320_Write_Byte(0x04,0x00);
AIC320_Write_Byte(0x10,0x00);
AIC320_Write_Byte(0x11,0x00);
AIC320_Write_Byte(0x12,0x00);//LOL driver is not muted
AIC320_Write_Byte(0x13,0x00);//LOR driver is not muted
AIC320_Write_Byte(0x09,0x3C);//Power up LOL and LOR drivers//0C
HAL_Delay(10);
AIC320_Write_Byte(0x00,0x00);//Initialize to Page 0
AIC320_Write_Byte(0x3f,0xd6);//d6//da
AIC320_Write_Byte(0x40,0x00);
HAL_Delay(10);
}

请帮我看看是哪出的问题？谢谢。
