Not sure how to use the LC3 Codec too compile a working sample code for 5340 Audio devkit

As of a couple weeks ago, the buyout process has been completed for LC3 and we no longer require an Evaluation or Sublicense Agreement.  Here are the links to Documentation and code github site.

not sure how to intergrade this into the Nordic Connect for desktop environment

Hello,

I am not certain what you are asking here, but I will try to explain some things about the LC3 library within NCS and the nRF5340 Audio application. Let me know if I am on the wrong track.

Yes, this is correct. The LC3 codec is now included as a library within NCS v2.1.0. This addition includes that you don't have to add the lc3 library manually by setting the nrf5340_audio group filter. The documentation for the application in the v2.1.0 release has been updated to reflect the change.

You can upgrade to NCS v2.1.0 through the Toolchain Manager within nRF Connect for Desktop. When the SDK is installed, you can build the nRF5340 Audio application with the build script provided in the sample or with the command line. Both methods are described in the Building and Running section of the application documentation you linked. Opening bash or VS Code from the Toolchain Manager will ensure that all environment variables are correctly set and both the build script and the command line method will work to build the application.

Does this clear up your confusion?

Kind Regards,

Maria
