https://devzone.nordicsemi.com/f/nordic-q-a/111457/extracting-cs47l63-driver-from-nrf5340-audio-dk-applicationAfter some considerable effort, I have extracted the CS47L63 driver from the nrf5340_audio application, and finally have the absolute bare minimum proof of concept code that builds and functions exactly as expected. But only if debug optimizations (-Ogen-USTelligent Community 13Sat, 25 Oct 2025 23:10:16 GMThttps://devzone.nordicsemi.com/thread/552401?ContentTypeID=1Sat, 25 Oct 2025 23:10:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:45d9ce4d-ddbc-4848-ae45-fbd33f5b01e1geoffF<p>Did you ever find a solution?&nbsp;</p> <p>I am also trying to salvage parts from the&nbsp;<span>nrf5340_audio application but it such a behemoth that using it as a base for understanding the various components of the audio dk is frustrating.&nbsp; Frankly it is surprising Nordic don&#39;t offer some smaller example projects to illustrates its functions more simply or at least at add support for the dk to some of their existing examples.&nbsp; I am trying to get the i2s echo example working on the audio dk - hence trying to extract the codec from&nbsp;nrf5340_audio to replace the one it uses.</span></p> <p><span>The&nbsp;nrf5340_audio project does not even build in VS Code, despite threads on here saying they were working on it years ago.&nbsp; Given Nordic have pretty much moved 100% to VS Code now seems fairly unlike them. </span></p> <p>There are many threads on here with audio dk queries without very good answers.</p><div style="clear:both;"></div>
