Tool/software: Starterware
The machine has Speaker and Line out, all through the 3100 output, the master through the I2S, I2C send data and configuration 3100.
After the boot, Speaker sound is very small (regardless of volume, even if the volume is transferred to the maximum, the sound is very small and no change), and Line Out is able to normal output, adjust the volume will respond.
3100 all the power supply are normal supply, through the oscilloscope monitoring, there has been no power-down phenomenon, only to restart the machine to return to normal.
I2C rate of 100K, and the master will be in the boot process before and after 2 times through the I2C configuration 3100.
Reproduction probability: 30%, attachment for register configuration.
Above, please help analyze the reasons, thank you!
