Hello,

Thank you for your patience. I recommend that you verify that the SW codec is successfully initialized, i.e. by logging the return code after sw_codec_init is called in audio_system.c.

Also, if you can share more of your logs that may be helpful to see more of the context. You can share the logs as text by using Insert->Code.

Best regards,

Maria

Good afternoon, the previous error was to see if it recognized the card, and when I inserted it, it did. I updated the SDK to version 3.1.1 and I'm still getting the same error.

Hello,

The return code -13 is -EACCES, which is returned when the software codec is not initialized. I can see some remnants of an error message above your shell command. Does that line or any previous error logs indicate that the SW codec fails to initialize/successfully set up?

Also, I want to add that the documentation for the SD card playback module is not available until nRF Connect SDK v3.1.0. If possible, please update your SDK to the latest tagged release (currently v3.2.1). By updating you will get the latest version of the SDK and nRF5340 Audio application and you can use our DN later on if you go into production with an LE Audio project.

Best regards,

Maria
