We are using tlv320aic2368I in one of our designs (Not as default audio codec). We are programming it through I2C interface.
The following registers we have written for the first time.
"Book 0 / Page 1 / Register 23: Lineout Amplifier Control 2 - 0x00 / 0x01 / 0x17 (B0_P1_R23)" with 0x09 "Book 0 / Page 1 / Register 22: Lineout Amplifier Control 1 - 0x00 / 0x01 / 0x16 (B0_P1_R22)" with 0x03
i.e. we have routed IN1L/AUX1L & IN1R/AUX1R to the LOL & LOR. We are able to listen audio.
But after this, we observed the following cases.
- we have turned off the power to the board and turned on again, we are able to listen the audio without any programming.
- We are applying reset, through software reset register (Book 0 / Page 0 / Register 01), still the IC is not resetting. it automatically playing the audio.
