Recently i've noticed that sometimes when sound is playing over the headphones (MM-100), there is some crackling noise, not the planar crackle, like bad signal crackling but very faintly. It's not unusable but it is distracting and irritating, most importantly it happens intermittently. I'm running headphones through fiio k5 pro ess and using the oratory preset for EqApo. When i tried to switch the usb port, the buzzing was insane and definitely unusable, there are like 2 usb ports out of 8 that do not constantly buzz, including the front IO. The usb 3.1 in particular produces the most buzz. I had dac/amps before this one but its only on this one that this happens and its weird, the two that do not buzz work 99.9 except the mentioned intermittent crackling. Switching to the onboard motherboard dac (Prime X370 Pro) the buzzing still continues unchanged, like on the 2 that ''work''. Now, when trying over the phone with the basic usb c to 3.5mm adapter, there is no crackling or buzzing at all, although i don't use any eq over phone. I can't isolate the issue specifically because its weird, it seems that headphones are fine but why would it have issues over on the pc side? Every other dac works as it should. Is there something on the dac's side that is faulty or on the pc's side? I also tried to uninstall and reinstall drivers for the k5, it didn't help.
