TLV320ADC3101 配置同样的gain,但左右通道录制的音频声音大小不同

工程师们,有人遇到过这种问题吗?设置同样的gain,但录出来的左右声道声音大小却一样。寄存器配置如下:eg:(reg,value)

(0x00, 0x00);
(0x01, 0x01);
(0x04, 0x00);

(0x05, 0x11);

(0x06, 0x04);
(0x07, 0x00);
(0x08, 0x00);
(0x05, 0x11);
(0x12, 0x81);
(0x13, 0x82);
(0x14, 0x80);
(0x1b, 0x00);
(0x3d, 0x01);

(0x00, 0x01);

(0x33, 0x50);
(0x3b, 0x00);
(0x3c, 0x00);

(0x34, 0x3f);
(0x37, 0xff);
(0x39, 0x0f);

(0x00, 0x00);
(0x51, 0xc2);
(0x52, 0x00);

MCLK=11.289MHz,输入源选择差分输入,
