TLV320AIC3101: Audio data from I2S DIN failed to playback via HPLOUT/HPROUT

Part Number: TLV320AIC3101
Other Parts Discussed in Thread: REG101, REG102

Hi,

In our design, audio_in connected to IN1RP/M and audio_out connected to HPLOUT/HPROUT. TLV320AIC3101 connected to MCU via I2S. So far we can record audio_in, but audio from I2S DIN failed to output to audio_out, no sound come out. We try to config  PGA_L  routed to HPLOUT, sound come out. We dump the registers:

SAMPLE_Tlv320_CfgAudio(enWorkmode=0,enSample=48000)
reg0 =0,
reg1 =0,reg2 =0,
reg3 =81,reg4 =80,
