Hi all,
Just a small update for you. 

I have gotten the board up and running and tested some of the capabilities to date so I am confident that the hardware design doesn't have any major flaws and all of the components are working as they should. My plan for the coming month of May is to slowly chip away at the datasheet to configure the TLV320AIC3254 Codec over I2C. I have been able to read and write its registers but am still trying to write the drivers for it on the RP2040. 

This leads to my call for help, does anybody know of any available drivers for this IC (TLV320AIC3254) out there? Also on a similar note, thoughts on how to generate the MCLK line using the RP2040? 

I am open to having a chat about perhaps sending over a sample PCB if you have the experience with what I am trying to do here.
