STM32F407G Dev-Kit LD1 Noise

Associate II

Hi! I've been following this tutorial to enter the world of audio dsp. The issue is that when I connect the board via USB, LD1 is always on (red) and I can hear a bunch of white noise at my output. When I power the board externally via 3V, LD1 starts to pulsate and I can only hear white noise when it's on. Thus my question is, can I disable LD1 somehow? As it seems to be interfering a lot with my I2S or ADC/DAC...
