Can not get Audio input line-1 to work.

I am experimenting with the DISCO-F746NG-AUDIO-DEMO and am not able to get the input audio Line1 to work. I changed the INPUT_DEVICE_DIGITAL_MICROPHONE_2 to INPUT_DEVICE_INPUT_LINE_1 in the AUDIO_DISCO_F746NG.cpp constructor. I have gone through the stm32746g_discovery_audio.c and the configuration of the WM8994 seem to be OK with respect to using input Line1. In advance thank you.
