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 and the schematics of our audio amplifier, can you please check and assist on us on this query
