Hi, something really weird is happening. I have a circuit that works perfectly with audio over usb, with a soft pot and a sharp IR distance sensor, but when I use the DAC (A14) it freaks out. It emits a really annoying high frequency, like really fast pulses. When I take the positive or the ground terminals of the IR everything works fine. I have other potentiometers in the circuit hooked up in the same manner, but just the IR makes that. I tried with two models of IR (the Sharp ones) and different cables, and it still happens. Even if I'm not reading the input, it's just a matter of having both ground and positive to make this sound. I tried all the positive and ground possibilities on Teensy (3.2).
Any help, please?
Ps: I'm not posting the code because it happens regardless of the code.
