nRF5340 audio DK WALKIE_TALKIE_DEMO build error

[gfgf2400a]

Hi, I am using nRF5340 audio DK PCA10121, NCS 2.1.1 I am following https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/nrf5340_audio/README.html#enabling-the-walkie-talkie-demo to have prj.conf with CONFIG_WALKIE_TALKIE_DEMO=y.

I got this undefined symbol error "c:/Projects/Amoeba/BLE-Firmware/central_comm_node/prj.conf:70: warning: attempt to assign the value 'y' to the undefined symbol WALKIE_TALKIE_DEMO".

Here is my complete build trace. Please advise, thanks.

Hi, 

Here is the PR https://github.com/nrfconnect/sdk-nrf/pull/9003.

I merged the PR changes to NCS v2.1.1. Look like C:\ncs\v2.1.1\nrf\applications\nrf5340_audio\src\drivers\cs47l63_reg_conf.h had changed (from input_enable[][] to line_in_enable[][]) to cause compilation error:

Hi, 

Please modify the definition to line_in_enable as https://github.com/nrfconnect/sdk-nrf/blob/70052d91a574987b458d3c1cf3988bac692fa2fc/applications/nrf5340_audio/src/drivers/cs47l63_reg_conf.h#L81
