I'm getting a lot of background white noise using a Sabrent USB audio device and the Adafruit 2.5W amp for mono sound. Everything is working, but I'm still getting a buzzing sound. It's less distracting when sound is playing, but very apparent when not (especially in the headphones).My power and ground are all coming from the Pi itself since I'm still checking everything before it gets set in. Could that be the issue? Any other suggestions?
I didn't find the right solution from the internet.
