ADAU1996A : TDM8 on the EVAL-ADAU196XAZ DAC development board using a Xilinx Data Input

Hello!

I'm currently trying to setup the ADAU1996A DAC Chip to output different channel sounds using TDM8 protocol. In the current configuration (Looking at the waveform below), the DAC should only output a sound out of channel 1 (channel 0 in the waveform). In spite of that, the DAC ends up outputting the sound to all channels based on the data of channel 1. I don't really know at this point if my data input is incorrect, or if the register settings in the DAC may be incorrect. Below is a waveform that represents what I am inputting into the DAC. The most important signals being db_clk (DBCLK), dlr_clk (DLRCLK), sound (The bit data inputted into the DSDATA1 pin), and channel[2:0] (The 8 channels being controlled using DSDATA1). There is also a picture of the register configuration in SigmaStudio.

Thank you
