STM32F769I Discovery board example project, voice output using speaker

[IWahe.1]

Greetings to the ST community,

I was using the example project provided by ST in "STM32F769I-Discovery\Applications\Audio\Audio_playback_and_record\EWARM" and found out that voice was being output through the headphones.

However I connected speakers to JP2 and JP3 each however no voice was being output. Although in "\Audio\Audio_playback_and_record\Src\waveplayer.c", the output is initalised as:

static uint8_t PlayerInit(uint32_t AudioFreq)
{ 
 /* Initialize the Audio codec and all related peripherals (I2S, I2C, IOExpander, IOs...) */ 
 if(BSP_AUDIO_OUT_Init(OUTPUT_DEVICE_BOTH, uwVolume, AudioFreq) != 0)
 {

Can I get some guidance what exactly is missing?
