Hey everyone,
I recently switched from an rpi 4 to a NUC 8 i5 acting as Roon Core, Roon endpoint, Spotify Connect, and Shairport receiver. All through Equalizer APO.
I had no issues with the pi setup, the NUC however, produces audible crackle, noise, hum, hiss, wheer, jeer, gurrr... This happens on both Khadas TB and RME BFP (non FS). I have tried different USB ports, different USB cables, a powered USB hub, different RCA cables, different inputs on the amp, different power outlets, and obviously different DACs. My amp doesn't have balanced inputs so that's not an option.
The confusing thing is that listening to the DAC signal with headphones there's no noise, but when fed into the amp, there's lots of noise. If the issue is with the NUC then why is there no noise in headphone out, and if it is with the amp, then why is the rpi not affected?
Any suggestions on what may be going on here is greatly appreciated.
