STM32F746 Discovery Board Speaker Out

Using Audio_Weaver_Designer_7.A.0.8 STMicro Edition, I am able to run an Audio Weaver AWD file with microphone input and audio output on an STM32F746 Discovery Board.

The Audio output is available on the 1/8" audio connector. Isn't it possible to have the output also available on the Audio Codec Speaker Out?

I tried the following without any success:

1. Edit SetupAudio(void) to include OUTPUT_DEVICE_BOTH instead of OUTPUT_DEVICE_HEADPHONE as follow:

2. void SetupAudio(void)
   {
       uint16_t nInputDevice;
       memset(AudioBufferIn, 0, sizeof(AudioBufferIn));
       memset(AudioBufferOut, 0, sizeof(AudioBufferOut));
       nInputDevice = INPUT_DEVICE_INPUT_LINE_1 | INPUT_DEVICE_DIGITAL_MICROPHONE_2;
       BSP_AUDIO_IN_OUT_Init(nInputDevice, OUTPUT_DEVICE_BOTH, uwVolume, I2S_AUDIOFREQ_48K);

   }   // End SetupAudio

3. Build and program target with new .bin
