Other Parts Discussed in Thread: TLV320AIC3100
Hi Team,
Customer is using AIC3110 on some Car ending equipment. They reported the issue as: When they are normally playing music from I2S to analog output, headphone or class D, when they changed the (Page 1 / Register 36)and(Page 1 / Register 40)volume bit, tried to change the volume, They said they tried every bit, but none of them could effect the volume. The volume does not change.
And they pulled the state bit of volume control, the seems the volume never be changed. They said all the clocks are applied, since they are normally playing the sound.
