你好!在3106的line-out可以听到line-in或者mic-in的声音,但是听不到i2s的声音,i2s的波形测试都正常,如果用一个转换模块pcm5102a(i2s转line-out)通过飞线的方式焊接i2s总线上也可以听到声音,这就说明adv7612输出的i2s是正常的
3106是从模式
请问3106哪里是不是没有配置好?谢谢!

引入的i2s的MCLK=12MHZ,WCLK=48KHZ,BLCK示波器测试有音频数据输入,但是LEFT/RIGHT_LOUT输出端就没有音频数据,请问怎么回事?
配置的相关寄存器如下:
tlv320aic31_write(IIC_device_addr[chip_num], 7, 0xa);/* FSref = 48 kHz */
/*left and right DAC power on*/ || soft_reset
tlv320aic31_write(IIC_device_addr[chip_num], 37, 0xc0);
/*left DAC not muted*/
tlv320aic31_write(IIC_device_addr[chip_num], 43, 0x0);
/*right DAC not muted*/ ~
tlv320aic31_write(IIC_device_addr[chip_num], 44, 0x0);
//left-dac
tlv320aic31_write(IIC_device_addr[chip_num], 82, 0x80);
tlv320aic31_write(IIC_device_addr[chip_num], 86, 0x08);
//right-dac
tlv320aic31_write(IIC_device_addr[chip_num], 92, 0x80);
tlv320aic31_write(IIC_device_addr[chip_num], 93, 0x08);
为什么就没有声音?
如果LINE1或者LINE2接入音频信号,做旁路输出bypss的话,tlv320aic31_write(IIC_device_addr[chip_num], 108, 0xff);
LEFT/RIGHT_LOUT有音频输出,芯片外围输出是正常的,
