STM32F7 Embedded coder - Simulink error in Parametric Audio Equalizer example

Hello Sir, I am using parametric audio equalizer example given by Embedded coder library. It works fine with microphone as audio in with audio line out, but it shows error when I select 'Line in' in Audio input block. it shows error that its not compatible with 'Headphone' in Audio output block. I have attached the screenshot of error. If its possible to solve or by changing a parameter, then please let me know.

Thank You.
