TAS5756M: GPIO2 have no signal output

aggil liang

Part Number: TAS5756M

Dear Team

We want to use GPIO2 for SDOUT, but now we can't get the I2S signal from the PIN 23. Below is our register configeration. Is there other register need to write ?

We want to SDOUT equal as SDIN.

Hi Aggil,

I notice that you are dealing with this issue in : https://e2e.ti.com/support/audio/f/6/t/824363.

Are the two questions the same issue?

I am thinking that maybe you can use l2C tools to write I2C commands to configure the device. Let me check afterwords.
