STM32F7 discovery audio line-in

Hi.
I've started to play with STM32F7 discovery. I got to DSP audio example from hands-on and I would like to use line-in instead of microphones. Unfortunately when I've changed
BSP_AUDIO_IN_OUT_Init(INPUT_DEVICE_DIGITAL_MICROPHONE_2, OUTPUT_DEVICE_HEADPHONE, 90, DEFAULT_AUDIO_IN_FREQ);
to
BSP_AUDIO_IN_OUT_Init(INPUT_DEVICE_INPUT_LINE_1, OUTPUT_DEVICE_HEADPHONE, 90, DEFAULT_AUDIO_IN_FREQ);

Only thing that's coming is noise. Could anyone help me to get line-in working?

Best regards
Konrad
