RE: When compiling nef5340 audio device, LC3 encoding and decoding mode is selected, and the header device is not available

Hello!

I would advise you to upgrade to NCS v2.0.0, as it contains major updates relevant to BLE Audio support, unless you have very good reasons to stay in 1.9.

Let me know if you still have issues with this.

Best regards,

Einar
