Part Number: TAS5731M

HI，

I set Master Volume to 4.5dB in TAS5731M GUI interface,the GUI shows master volume's I2C=0X07,but the cfg file do not have the 0X07 vlue.I want to know the reason about it.

I try to add X07 27 to my code.after the system start up finished,I read the 0X07'vlue is 30(default vlue).How can we wirte a different vlue to 0X27 to change Master Volume

Hello Oasis,

When you say it shows a "null," can you please attach a screen capture?

Additionally, I know you say that "it is the only null" does that mean you have tried to write to other registers and have read back what you wrote?

All the best,

Carolina
