TLV320AIC3104: Application issues of chips

Tonyx.wu

Part Number: TLV320AIC3104


Tool/software:

After powering on, there is sound coming from the MIC string to the speaker and the loopback is not turned on. The audio playback is normal. Can you help me identify the hardware and software issues and how to solve them? For example, which register setting is related to this?
In addition, QIIC is used to read the value of the codec register. AT+QIIC=<1>,<2>,<3>The third parameter is the register address, which reads its value
