Sound effect during playback occurs.
Recently i've noticed that sometimes when sound is playing over the headphones (MM-100), there is some crackling noise, not the planar crincle, its 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 10 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.
If the ground pin isn't connected, it can cause electrical issues. In EU, check your wiring rules and ensure proper grounding is followed. Consult local regulations or a professional for guidance.
If your ground is floating, it means it isn't linked to Earth ground—usually not safe or advised. This issue often appears in older homes. Signs include static sounds in your audio, strange behavior of electronic gadgets, flickering lights, and even electric shocks. I referenced a photo as an illustration, but you should locate something similar that matches your outlet type. How do your outlets look, by the way?
