TLV320AIC3104: Standby mode confirmation

Part Number: TLV320AIC3104


hi Team:

 my customer use TLV320AIC3104 as below block diagram. customer report that after wake up again the  system, there is no sound output. but it is okay to work after power on/OFF.

 i just check the register of wake up and register of power on, it is same.

 so i think there is no difference between power on / wake up mode for the codec.it maybe something not work in the signal chain.

 but i just want to check whether there are some registers that we can put this device in sleep or working status register can be check.

 tks!
