hi,
We have designed our custom board with TAS5755MDFD audio chip and interfaced it to Nvidia TX2 SOM ( where it runs with linux operating system in it ), but we can't able to drive audio signal to the speaker. We have bought a EVM for this audio chip and verified its working via the provided GUI tool for windows. Currently we are facing problem in board bring-up, where we cannot able to receive the audio signal via speaker output. Please find the below register setting we have used.

We have used the amplifier in PBTL configuration and AD mode, please find our register settings as below, request you to share any register setting for our configuration mode
Added we have read the error register in the chip and it shows 0x00 value always even if we clear and read the register ( means no error )
can you please check the register settings and assist us to solve this.
Also how can we check whether the amplifier is bring up successfully? is there is any register or any procedure to find the status of the chip?
